SENTINELS

PREPARING FOR THE RAPIDS

A hot meal and solid sleep leave us refreshed as we prepare to cross to the west side of the paddling route of the Bowron Lake circuit. We must first face several kilometres portaging muddy trails to meet up with the Isaac River and then paddle rapids to grade two. We enjoy a world of sensory bliss punctuated with thrilling spurts dodging stumps and snags.

EXPLORATION: LAKE ISAAC

Like most mountainous areas, Bowron makes its own weather system and it appears you get everything in a 24-hour period. In fact, whatever weather you are enjoying seems to change 40 minutes later; good for rain, bad for sun. Wisps of cloud that seemed light and airy only hours early have become dark. Careful to hug the shore, we are ready for a quick escape from lightening as thundershowers break.

URSAVUS: CLOSE ENCOUNTERS

Mid-way through a paddling trip in the beautiful Bowron lake Circuit, we reach the end of Babcock Lake and prepare for our next portage. Philip and I are photo bugs and I get my camera out to take advantage of the angle of the sun and the eroded rounded hilltops of the Quesnel Highlands that stand as backdrop. Looking around for material to shoot, Leanne pipes up and says she can see a moose a little ways off and that it appeared to be heading our way. Yes, heading our way quickly with a baby moose in tow. I lift my lens to immortalize the moment.... We three realized the moose are heading our way in double time because they are being chased by a grizzly at top speed.

"Grizzly!" The three of us gather together to prepare for what is racing towards us.

A full-grown moose can run up to fifty-six kilometres per hour, slightly faster than a Grizzly. They are also strong swimmers. Had she been alone, Mamma moose would likely have tried to out swim the bear. Currently, however, this is not the case. From where we stand we can see the water turned to white foam at their feet as they fly towards us.

We freeze, bear spray in hand. In seconds the three were upon us. Mamma moose, using home field advantage, runs straight for us and just reaching our boats, turned 90 degrees, bolting for the woods, baby moose fast on her heels. The Grizzly, caught up in the froth of running and thrill of the kill, doesn’t notice the deke, hits the brakes at the boats and stands up, confused.

Her eyes give her away. This was not what she had planned and the whole moose-suddenly-transformed-into-human thing is giving her pause. Her head tilts back as she gets a good smell of us. Suddenly, a crack in the woods catches her attention. Her head snaps round and she drops back on all fours, beginning her chase anew. Somewhere there is a terrified mother moose and calf hoping the distance gained is enough to keep them from being lunch. I choose to believe both moose got away with the unwitting distraction we provided, but I’m certainly grateful we did.

The Lakes are at an elevation of over 900 m (3000 ft) and both grizzly and black bear sightings are common. Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage having just met one of the larger descendents.While we’d grumbled only hours earlier about how tired we were feeling, we now feel quite motivated and do the next two portages and lakes in good time.

Aside from the gripping fear that another bear encounter is imminent, we enjoy the park-like setting, careful to scan the stands of birch trees for dark shapes now posing as stumps.

Fortunately, the only wildlife we see are a few wily chipmunks, various reticent warblers and some equally shy spruce grouse.

HORNBY ISLAND: LAMBERT FORMATION

The fossils of Hornby Island off the coast of Vancouver Island contain some of the best preserved fossils in British Columbia. Many species of ammonites (mainly Pachydiscus), crabs, bivalves, sharks teeth, echinoids, wood and bone can be found in the Cretaceous shales and concretions of the Lambert Formation at Collishaw Point

AMMONITES OF SOKOJA, MADAGASCAR

There is delightful suturing on this lovely ammonite, Holcophylloceras mediterraneum, (Neumayr 1871) from Late Jurassic (Oxfordian) deposits near Sokoja, Madagasgar.

The shells had many chambers divided by walls called septa. The chambers were connected by a tube called a siphuncle which allowed for the control of buoyancy with the hollow inner chambers of the shell acting as air tanks to help them float.

We can see the edges of this specimen's shell where it would have continued out to the last chamber, the body chamber, where the ammonite lived. Picture a squid or octopus, now add a shell and a ton of water. That's him!

They were prolific breeders that evolved rapidly. If you could cast a fishing line into our ancient seas, it is likely that you would hook an ammonite, not a fish. They were prolific back in the day, living (and sometimes dying) in schools in oceans around the globe. We find ammonite fossils (and plenty of them) in sedimentary rock from all over the world.

In some cases, we find rock beds where we can see evidence of a new species that evolved, lived and died out in such a short time span that we can walk through time, following the course of evolution using ammonites as a window into the past.

For this reason, they make excellent index fossils. An index fossil is a species that allows us to link a particular rock formation, layered in time with a particular species or genus found there. Generally, deeper is older, so we use the sedimentary layers rock to match up to specific geologic time periods, rather the way we use tree-rings to date trees. A handy way to compare fossils and date strata across the globe.

BLUE JAYS: KWASK'WAS

If you live in North American, there is a high probability that you have seen or heard the bird song of the Blue jay, Cyanocitta cristata (Linnaeus, 1758).

Blue Jays are in the family Corvidae — along with crows, ravens, rooks, magpies and jackdaws. They belong to a lineage of birds first seen in the Miocene — 25 million years ago. 

These beautifully plumed, blue, black and white birds can be found across southern Canada down to Florida. The distinctive blue you see in their feathers is a trick of the light. Their pigment, melanin, is actually a rather dull brown. The blue you see is caused by scattering light through modified cells on the surface of the feather as wee barbs.

Blue jays like to dine on nuts, seeds, suet, arthropods and some small vertebrates. 

If you are attempting to lure them to your yard with a bird feeder, they prefer those mounted on trays or posts versus hanging feeders. They will eat most anything you have on offer but sunflower seeds and peanuts are their favourites. 

They have a fondness for acorns and have been credited with helping expand the range of oak trees as the ice melted after the last glacial period.  

Their Binomial name, Cyanocitta cristata means, crested, blue chattering bird. I might have amended that to something less flattering, working in a Latin word or two for shrieks and screams — voce et gemitu or ululo et quiritor. While their plumage is a visual feast, their bird chatter leaves something to be desired. 

Their cries are quite helpful if you are an animal living nearby and concerned about predators. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, a Blue Jay is known as kwa̱skwa̱s

The Kwak’wala word for blue is dzasa and cry is ḵ̕was'id. For interest, the word for bird song in Kwak'wala is t̕sa̱sḵwana

GLACIALLY CARVED FJORD: SEA TO SKY



















A short 90-minute drive north of the city of Vancouver, the nation's gateway to the Pacific, is a recreational Shangri-La that attracts four season adventurers from around the globe to ski, board, hike, mountain bike, kayak and climb the local peaks.

This treasure trove wilderness playground stretches along the breathtaking Sea-to-Sky Highway affording breathtaking views of the Pacific as it follows Highway 99 north out of the sparkling gem of Vancouver from Lions Bay, through Squamish and Garibaldi and into the picturesque Whistler Valley.

As you drive out of the city, look at the mountains to the north. Grouse, Cypress and Seymour mountains provide easy access skiing for the happy winter adventurer and a beautiful backdrop to the young city of Vancouver, Canada's third-largest metropolis, year-round.

While the city sits on relatively young sandstone and mudstone, the North Shore Mountains are made from granite that formed deep within the Earth more than 100 million years ago.

Following Highway 99, you’ll hug the coastline of Howe Sound, a glacially carved fiord which extends from Horseshoe Bay (20 km northwest of Vancouver) to the hamlet of Squamish. The road is perched high above the water, blasted into the rock of the steep glacial-valley slope and has been the chosen path for First Nation hunters, early explorers, the miners of the Gold Rush and now the rush of tourism.

Carved from the granitic mountainside high above Howe Sound, this scenic pathway has been a rich recreation corridor and traditional First Nation hunting ground for many years.

Steeped in a First Nations history, bountiful wildlife and gorgeous vistas, the Whistler corridor is considered by many to be one of the most beautiful spots on the globe with something for everyone.
