A Day Off

IMGP0438
A rare weekday off for just myself today. So while Louise was diligently at work preparing for the fall university session, I spontaneously decided to start the day with a quick paddle up our home waters of The Gorge. See, Louise? I can be spontaneous!
Whatta ya mean this isn't what you meant?

Anyway, I had barely started when I spotted something off to my left.

Yes, a heron. And I'm going to warn you now. It's going to be another one of those posts filled with heron pictures. They're obviously doing well this year on the Gorge, and are making a comeback in Beacon Hill Park as well, despite being virtually wiped out there by eagles a couple of years ago.
IMG_1044

Okay, let's get the rest of the heron pictures out of the way. I passed a couple more as I kayaked up the Gorge towards Portage Inlet.

I passed under the bride into Portage Inlet....
GOPR3973
...as the early morning sun beamed down. We've had some hot days during the last month or so. Yesterday was a scorcher, today was shaping up to be another.

I spotted a bald eagle in a tree, or at least what I thought was an eagle. Scanning trees for a blob of white has been a good method for finding eagles, at least until now. Today I was fooled by a seagull.
IMG_1056
Well played, seagull. You win this round.
Actually, you can see it in the trees in this shot if you look closely.
GOPR3775

A few minutes later, I paddled through hundreds of floating white feathers. Since I had seagulls on the brains at that moment, I tried to imagine what would have caused all the seagulls in the area to suddenly go bald. No wonder he was hiding in a tree!
GOPR3802
On further reflection, there just aren't that many seagulls around here. So unless the local swans had suddenly exploded for no good reason, I'm guessing the culprit here is geese. There are a lot of transients heading south right now in addition to the locals, and I suppose they must molt or something. I guess. I dunno, who am I, Dr.Goose?
I soon encountered the local swans....
IMG_1064 copy
....and since they obviously have not spontaneously exploded, my geese theory is looking better all the time.

Before heading back, I looked for some of the gelatinous egg sacks that we see on the sandy Inlet floor in the fall. As it was a low tide, I couldn't do a lot of exploring without bottoming out but I did spot a few of them.

Not all of my animal encounters were with winged animals.
IMG_1065 copy

As I returned to my put in, I saw the same heron that I saw when I launched, still working the same fishing spot.
IMG_1068 copy
IMG_1075 copy
I don't know why he stayed there. I watched him for a long time and not once did he strike for a fish.

With that, the paddle came to an end. I need to figure out a way to not go to work tomorrow so I can paddle again!

Seagull With A Mohawk

Louise has family visiting in town this in town this week, so she and I could only sneak away for a quick paddle up The Gorge today.
Project1

We rolled the kayaks down the hill, entered at the Victoria Canoe and Kayak Club launch point, and we were off. The tide was flooding under the Tillicum Bridge so we went for a quick look and saw a lone seal, far away from the open ocean, enjoying a playful ride in the current.

A few minutes later we discovered one of the more interesting seagulls we've seen. May I present Seagull With A Mohawk.
2011-09-05 The Gorge_0099 copy
We first noticed him as he flew to the shore carrying some sort of shell. We thought that it may have been a crab shell, or maybe a clam. (I don't do shellfish, a shell is a shell.) Anyway, he landed on shore and spent a few minutes eating whatever was on the inside of the shell, then looked up and saw that there was another seagull on the beach a few metres away. This second seagull was paying no attention to Mohawk (or his lovely breakfast) but clearly Mohawk was feeling threatened so he dropped his meal and ran up to the other seagull and did a bit wing-flapping and squawking. He returned to his meal, but seagull #2 didn't get the hint, and Mohawk ran up and squawked again. He didn't take "no" for an answer and forced seagull #2 off the beach and into the air. Mohawk pursued him into the air, hoping to get the point across that he was not welcome. Louise and I watched the aerial dogfight, the two seagulls swooping and diving over our heads. Also watching were two crows that had sneaked up to Mohawk's dropped meal and finished it off. Mohawk returned to his empty shell, sighed (really! I swear he did!) and flew off.
A moment later....
2011-09-05 The Gorge_0022 copy
...he had dredged up another shell and was finishing off the insides.

Cormorant Tree, often covered in cormorants, held only one today.
2011-09-05 The Gorge_0012 copy

We continued on into Portage Inlet where the herons were out in force today.
2011-09-05 The Gorge_0035 copy

Mohawk wasn't the only bird having good luck with food.
2011-09-05 The Gorge_0066 copy

I thought I was cleverly sneaking up on this heron from behind. No such luck -- he knew I was there.
2011-09-05 The Gorge_0083 copy

We also saw a few of the gelatinous egg sacks that we see in the waters here every fall. They seem to be a few weeks behind, but then everything is behind after the lousy spring.
2011-09-05 The Gorge_0114 copy
The egg sack is the little round thing in the middle. The other brown lumpy things are sponges.

There's a lot of geese around now. They know winter is coming and so are heading south and using the parks in the area as a rest area.
2011-09-05 The Gorge_0072

With only limited time today, we quickly turned back.

Waiatt Bay, Quadra Island

This summer, I got the chance to do something really special. As a volunteer assistant, I joined a biology project. A friend of mine in Straitwatch passed on an appeal from her friend Amy for volunteers to stay at an isolated campsite on Quadra Island, and take samples from beaches. Paddling skills would be an asset. I joined three other volunteers and Amy for five days on the shores of Waiatt Bay. All these photos were taken by Amy Groesbeck, earlier this summer at similar trips. You won't see any photos of me in this post. You wouldn't want to. The day before the trip, I went to the dermatologist and had eight pink fleshy moles burned off my face with liquid nitrogen. Yuck. A good week to be out in the middle of the woods and the sea, away from most people. It was a good time -- I got on the water every day in small boats, and paddled miles of unfamiliar shorelines.



There's an app for that
Our transportation from Heriot Bay to Waiatt Bay at the north end of Quadra Island was on a boat called the Gung Ho, skippered by Harper Graham. He has a sensible manner that makes passengers feel confident that he knows where he's going and what he's got to do to get there. Of course he knows! On the dashboard in his wheelhouse, next to the throttle controls for the boat's engine and a GPS locator, lies an iPhone in its rubbery case. Yup, an iPhone. He took a text message or two before we finished motoring out of Heriot Bay. He also opened up an app or two and swiped at the phone's screen as he approached the islets in the bay. Perfect navigation. There's an app for that, apparently. The bay is sheltered with several small islands that make up Octopus Islands Marine Park. Though it's only an hour away from Heriot Bay, Waiatt feels really isolated. That's partly because there's only one cabin visible along the shore, and partly because the second-growth timber has gotten pretty thick so the logging clear-cuts are all grown back in.
Here's a photo that Amy took of the place we camped, on the north shore of Waiatt Bay at the place the chart calls "Log Dump." This little cove has a stream running into the bay, and a midden where we camped, all thoroughly stomped on by the logging done here. Two old sheds and a camper are all falling to pieces in the trees. To see lots of photos of how Amy Groesbeck investigates clam gardens, go to her Flickr page and check out the right hand column of photo galleries. Some of them are labelled "Clam Garden 2011 - Trip 1" which took place in April 2011, through Trip 4 which took place in late June 2011. Those are the ones especially clam-appropriate.

All I have is a red canoe, three paddles and the truth(with apologies to U2 and Bono)
The skills to handle small boats are practical skills, with real-life applications for modern work in the sciences. One field that puts canoes and kayaks to serious use is... intertidal biology! At least, it does here on the wet coast.
We set out with two ancient canoes -- one green, one red -- and my five-year-old little inflatable kayak. The photo Amy took shows a dark green boat she used on an earlier trip this summer. The canoes were laden with highly technical scientific sampling equipment. That's 5-gallon plastic pails, garden trowels, rubber-palmed garden gloves, spiral-bound notebooks and Zip-Loc freezer bags. Okay, Amy had a transit of some kind with a laser level, too. And here's Amy holding some squares she made, 25 cm on a side made out of 1-inch PVC tubing, so we could dig holes exactly 25 cm across. We had to dig them 30 cm deep, which is exactly the length from my elbow to my knuckles. I love the precision of scientific work! In a few beaches, there were experiments placed where Amy buried hand-made mesh bags holding living clams.
Oh, and I was also trained in how to make a sampling device. A kitchen scrubber called a Tuffy was attached to a ten-inch piece of rebar with a cable tie. Easy as pie. After the rebar was pounded into a clam garden, the Tuffy would sit there for four days, collecting anonymous sludge and (with any luck) clam spat. Apparently, intertidal biologists have been trying to figure out how to collect clam spat, and inventing various devices. Someone lucked into using kitchen scrubbers, and found that the Tuffy brand was particularly effective. Did I mention that this project had some funding from grants? Your tax dollars at work, and very efficiently, too. Why waste a biologist's time hand-knitting spat collecting filters when an affordable commercial alternative is easily available. The fun part is pounding the rebar into the garden, when the pounding has to be done underwater. Smack! Smack! into the water. "Science! Doing it all for science!" Spit out muddy sea water. "I'm still having fun!"
Dunno what YOU did on your vacation, but I sat on muddy beaches, dug holes, and collected clam spat. I didn't even ask if spat was gametes or zygotes. I wasn't the one picking up the Tuffy scrubbers and putting them in Zip-Loc freezer bags, and I didn't really need to know. Nature's Art
On one island owned by a family that Amy knows, there's a cabin, hidden in the trees. It's decorated with all kinds of handmade art objects, made from wood and beach materials and boating materials. Visitors to the bay have been bringing their art objects here for years! When we got back to our camp at the log dump site, I took out my knitting and made a sweater. A little one, doll-size. The next day, we found a piece of driftwood and made a little person to put in the art cabin.


All in all they're just another rock in the wall
If you look over a clam garden at high tide, whether from a boat or from the shore, you probably wouldn't see anything to tell you that this is a place shaped by human gardeners.
When the tide is a little lower than full, you might guess at the shallows near shore, usually in a small bay or between two rocky points. But when the tide is low, approaching a zero tide, the clam garden is revealed.
From shore it looks like a flat, almost level shallow beach. It's mostly free of rocks bigger than your head. Most of the beach is sediments mixed with small stones and bits of broken clam shell. The clam shell hash was added deliberately, to change the local pH of the water and send chemical messages to floating clam spat that here was some good clam habitat to settle down and grow! At the edge of the garden is a rocky ledge. Most of these ledges don't stand up much higher than the level of the beach, maybe ankle-high. But if you look past the edge of the ledge, you can see that the sea bottom drops down suddenly. You're standing at the top of a wall made of rocks piled on rocks. One of these walls can be as high as three or four metres or more above its underwater base. Most of the visible rocks look small enough for one person to have rolled down the beach into place, about twenty to thirty centimetres across. The rocks at the bottom of the wall three or four metres or more underwater may be larger, maybe half a metre across or bigger. But that's really enough talking that I can do about clam gardens. To learn more about them, check out the totally awesome book Clam Garden by Judith Williams. You can read more about it at the publisher's website. There's a copy in the Greater Victoria Public Library!

A bird in the hand is worth a snake in the shallows
We got to see lots of wildlife, around the shores of Waiatt Bay. My little kayak is so quiet that I could sneak up on these animals, shyer than their city cousins in Cadboro Bay. A few seals swam by to check out our boats. Raccoons like clam gardens! A couple of times we saw two or three raccoons waddling over the flats at low tide, digging for clams and various invertebrates. A mink poked out its head from the shoreline bushes to look at the canoes that had just gone by, then stare at me and squeak "oh crap!" before darting away. And right in our camp, a little brown weasel came scampering by and glared at everyone. For birds, there were ravens watching our every move, as well as kingfishers and a hummingbird, and a large eagle. I'm sure that we all were very glad that no black bears or cougars came by for a visit.
The most striking animal sighting was when Sara squeaked while sitting on a rocky ledge one afternoon. "A snake!" she squawked. A garter snake was sunning itself on the ledge beside her. When it slithered into the lukewarm sea water, our overjoyed amateur naturalists joined the actual biologists. A snake that swam in sea water! oooOOOoo!

Well, maybe the most striking animal was the polychaete, a bristly marine worm that snaked out of a tunnel in the side of the sampling hole that Sara was digging. Another squawk announced her shock at the arrival of the sandworm. This probably wasn't the kind of polychaete that the Kayak Yak paddle group found in Portage Inlet, making jelly ball egg sacs. That worm, according to Dr Kelly Sendal, probably looks rather like a bratwurst. This one in Sara's gloved hands looked more like a giant pink earthworm with tiny millipede legs. She carefully put it aside and went back to digging. And found another one in her next hole. Only a tiny squawk that time. Tough gal!

I love your lab!
The first time we catalogued clams, both living clams and the shells of dead clams, our group gathered under the tarp over our kitchen area. Seated on five-gallon pails, we hunched over our shells. Annemarie sorted shells, Amy and Kim measured shells with calipers, Sarah and I recorded the measurements in Amy's notebooks. Plenty of banter. "Clam me," I said. "All Clams, All Dead." A rain squall fell around us, and we got chilled and stiff before we were done and dinner could be made. The second time was much more idyllic. That afternoon was sunny, so after lunch on a rocky slope below a midden across the bay from camp, we set up the calipers and notebooks. Each of us moved into the shade or sunshine at will by shifting a couple of feet on the moss. Our postures were not hunched this time, but varied from leaning on one elbow like a diner at a Roman feast to laying back against rocky slopes perfectly designed to support our backs and heads. More banter, as living clams were found among the dead samples and a dead clam among the living samples. Zombie clams don't groan "braiiinnzz", we decided, because they don't have brains. They call out for nerves.Looking out across the bay was wonderful. I'd always thought that doing science involved wearing lab coats, not bathing suits or my shortie wetsuit. This place was much nicer than a basement lab somewhere. "I love what you've done with your lab!"

In an Octopus's Garden
We came to a clam garden one day that had an unusual living thing at the edge of a particularly high wall. It looked rather like a dahlia flower made out of yellowish jellyfish. "What the heck is that?" Amy wondered out loud. "A squid's egg sac?"
"Or an octopus's egg sac?" I suggested. "There are supposedly a lot of octopus around here. This is Octopus Islands Marine Park, after all." That didn't seem likely. Octopus mothers usually put their egg sacs in sheltered places, and protect them till the little ones hatch. But I found photos online of octopus egg sacs that look pretty much like what we saw.
We got to work taking samples, and Amy wrote notes in her books. When she asked "What shall we call this beach?" there was really only one name to consider: Octopus's Garden.

Here Comes The Rain Again
The weather was almost perfect -- very little breeze on the water the second day, and a half-hour rain sqall were the only variations from sunny and mild. In this sheltered bay the ocean water gets about as warm as it does anywhere along the coast, so it felt much warmer than where I usually paddle near Victoria. There were some two dozen sailboats anchored in sheltered places around Waiatt Bay, the most crowded that Amy had ever seen this area. Nights were cool but not really cold. And just in case perfect was asking too much, an hour before the Gung Ho returned to take us back to Heriot Bay, the clouds opened up. All our tents were soaked as we stuffed them into their bags. But it was still fun! And I sure hope to do it again next year.

Failed at Finding a Whale?

"The water is like glass this morning. You should really go out in your kayak," my partner said Monday morning, after he returned from walking our landlady's dogs. I accepted the advice, got into my wetsuit and stacked gear in my Eliza. After all, someone saw a grey whale out by Ten Mile Point on Sunday... maybe I'd be lucky and see it too!

Rolling down to the beach was fine. Gyro Park on Cadboro Bay is a great place to launch, whether you're rolling a kayak on wheels or unloading a canoe from a car roof, or hauling a rowing dinghy on a little trailer. Any changes that Saanich Parks ever makes to this park should take small boats into consideration, and make it easier rather than harder to bring a boat to the shore. (Saanich has a survey online here until July 15. Be sure to tell them what you want for the park as future renovations are planned!)


The tide was low and still receding. Though the water wasn't quite glassy, it was a calm day. Before long I was out at Evan's Rock and looking about optimistically for a grey whale. Nope! none to be seen. Maybe it was still hanging around, but if so, it was hiding well off-shore. It would be smart not to come close to shore with the tide so low. I went along the Smuggler's Cove area over to Cadboro Point, looking at all the rocks which are normally just visible under the water.


It was a good time on the water. And even if I completely failed at seeing a whale, there were plenty of other things to see. A big eagle flew overhead. There were at least three ravens, too, and along the rocks a couple of oystercatchers were scrambling. The seal that hangs out around Flower Island seems to have a new baby this year... at least, there was a little seal head bobbing up near her head as she watched me paddle past the island. And otters! I saw three separate groups of otters out and about. Low tide is the time when the coastal buffet opens for them, and they scramble all around the rocks and through the shallow water. At one rock I saw a big white starfish among the seaweed, and a big jellyfish the colour of a poached egg.


So, no whale, but lots of other animals. That more than made up for pulling a muscle tugging my kayak up the steep ramp of soft, dry sand.


Oh, and the next morning Bernie and I walked the dogs over to Telegraph Bay and found another animal on the beach of little stones. A polychaete! In English, that's a bristly marine worm. This one looked like a big gray earthworm, like a night crawler about fourteen inches long. I found a drawing online of a polychaete. The Arenicolidae are common intertidal sandworms that look much like this one did.


The website had a page with taxonomic questions so that it was possible to figure out which particular bristly marine worm we might have found. Some of them are more bristly, others more wormy... and a few of them are freaky weird. Now, most people have less interest in marine worms than kayaks, I know. But since members of our paddle group have at different times found tube worms, fire worms, and the egg sacs of an unidentified marine worm, well, I found it interesting to look through this website. There were sketches of many families of marine worms, from the feather-duster-style tube worms to sea mice and things that are like stinging centipedes. Most of the drawings came from a book by J.H.Day, Polychaeta of Southern Africa, published in 1967 by the British Museum Natural History.

It would be nice to see a whale from my kayak, at a proper distance, but it's ok with me to see all these other animals that come out to play on a mild summer morning.

Seeing Red

It's hard to believe that some of us have been off the water for over a month. And in the middle of mostly sunny summer weather, no less! As the old saying goes, life happens.
There were family get-togethers, injuries, work obligations, and a weekend of bad weather that fouled-up paddling plans for the last few weeks. But now the weather's great, we've quit our jobs, the injuries have healed, and we've divorced our families, so now we are back in the paddle again.
And it's not like we ignored kayaking during the layoff. Far from it. Both Louise and I ordered new kayaks from the good folks at Ocean River, and they arrived yesterday.
2008-09-14 Gorge Portage 004
Louise bought a Delta Seventeen Sport (on the right). It's promises to be a little more edgier and playful than her old Fourteen5.
I went with the Delta Eighteen5 Expedition (on the left). The cockpit is a little bit roomier for my legs, which I like, yet still fits good in the hip area. It tracks nicely and goes quick, too.

Louise launches her new boat for the first time.
2008-09-14 Gorge Portage 030

We were joined by Paula (in Commando Mode) for an inauspicious first paddle into Portage Inlet, then down The Gorge.
2008-09-14 Gorge Portage 035

It's was a gorgeous day for paddling, and other people clearly had the same idea. Only moments after putting in, Richard and a friend paddled by us. They put in somewhere down the other end of The Gorge and had had to portage over the Tillicum rapids.
2008-09-14 Gorge Portage 042
They were going to head up Colquitz Creek, while we were going the far side of the Inlet to look for more jelly goobie egg sack thingies. So after we paddled together for a while, they went right, and we went left.

We headed around the point into egg sack country.
2008-09-14 Gorge Portage 049

We finally found more of the egg sacks. We thought about trying to get one and open it up, but it seemed too dangerous. (We all know what happened to John Hurt when he tried.)

Every other time I've been here, I've never managed to get a picture of the train...until today.
2008-09-14 Gorge Portage 015

We saw the swans again. It looks like they are the darlings of the Inlet. This gentleman stopped his Sunday chores to sit on his dock and feed them.
2008-09-14 Gorge Portage 019

We paddled back past our starting point and down The Gorge where the geese were plentiful....
2008-09-14 Gorge Portage 083

...so plentiful that they were guarding the beach preventing us from landing.
