40 DEGREES OF LATITUDE
Four individual raindrops falling on these high peaks could easily end up thousands of miles apart -- one flowing north to the Beaufort Sea, another reaching the the Gulf of Mexico, a third would be absorbed into Hudson Bay to the east and the last into the vast Pacific.

OKANAGAN ARC
The grouping includes the fossil sites of Driftwood Canyon, Quilchena, Allenby, Tranquille, McAbee, Princeton and Republic. These fossil sites range in time from Early to Middle Eocene, and the fossil they contain give us a snapshot of what was happening in this part of the world because of the varied plant fossils they contain.

CATACLYSMIC FORCE: THE BUILDING OF BC
How early is early is a matter of perspective. Some 270 million plus years ago, had one wanted to buy waterfront property in what is now British Columbia, you’d be looking somewhere between Prince George and the Alberta border. The rest of the province had yet to arrive but would be made up of over twenty major terranes from around the Pacific.
The rock that would eventually become the Cariboo Mountains and form the lakes and valleys of Bowron was far out in the Pacific Ocean, down near the equator. With tectonic shifting, these rocks drifted north-eastward, riding their continental plate, until they collided with and joined the Cordillera in the Pacific Northwest and helped to shape British Columbia.
Continued pressure and volcanic activity pushed and shoved, sculpting the tremendous slopes of the Cariboo Range we see today. Repeated bouts of glaciation during the Pleistocene carved the valleys and mountainside into the slightly smoother finish we see today. Wish I'd been around to stake a claim, even a little bit earlier... land as far as the eye can see... open vistas... and all for a penny.
The image above was taken from a jet ranger helicopter on the way to the fossil exposures near Castle Peak. I've flown in many times to search for exquisite Hettangian ammonites. These extinct cephalopods, now find high in the rockies, lived in the open ocean while BC was still being formed.

HORNBY ISLAND PALEONTOLOGY
Hornby also has some of the best preserved fossil specimens of the Pacific Northwest. Many species of ammonites (mainly Pachydiscus), crabs, bivalves, sharks teeth, echinoids, wood and bone can be found in the Upper Cretaceous shales and concretions of the Lambert Formation. Interestingly, they are remarkably similar to the ones you find in the French and Tamil areas of Pondicherry, India, telling us a great deal about what was happening back in the Maastrichtian some 70-million years ago.
If you happen to find yourself in Pondicherry, be sure to take in the exceptional cuisine and fossils at Thriuvakkarai. Photo by Tina Beard, beautiful friend and artist, on a particularly lovely afternoon.

QUARTZITE KIND OF BLUE
It is striking how much this scene fits exactly how you might picture pristine wilderness paddling in your mind’s eye. No power boats, no city hum, just pure silence, broken only by the sound of my paddle pulling through the water and the occasional burst of glee from one of the park’s many songbirds. Somewhere in the back of my head Miles Davis is working through Kind of Blue, in time to the wind and my slow, smooth strokes - perfect pairing for this lazy day.

THROW ANOTHER SHRIMP ON THE BARBIE
Planktos, a California-based company that sells “carbon credits” to businesses looking to reduce their carbon footprint and contribution to global emissions has been taken down by a swarm of shrimp. They had planned to harness the photosynthetic power of algae to lower greenhouse gases.
Algae come cheap, requiring light and water. They also require iron, which may be the sixth most abundant element in the Universe, but still relatively rare in the ocean. The small bits algae utilize are blown in by the wind and runoff from rivers and streams.
While some scientists and environmental groups object to their plan fearing harmful changes to the ecosystem, Planktos went ahead and dumped a hundred tons of iron dust mixed with seawater into international waters off the coast of the Argentina.
Expecting a plankton bloom and carbon credit riches to follow, their plans were literally eaten alive by a swarm of algae-loving shrimp. They did get their bloom, but it was not the algae they were expecting.
Instead of large diatom algae, they got millions and millions of haptophytes, a tiny algae common in the open ocean and extremely abundant in the fossil record. They are also the fellows responsible for the white foam you sometimes see on the edge of beaches.
Most importantly, however, they are the food of choice for the equally common copepod, a shrimp-like crustacean who complete with krill for forming the largest animal biomass on earth. And perhaps, having the largest appetite.
Sometimes brilliance arises from thinking outside the box. Sometimes not. The copepods ate all the haptophytes and Planktos' dreams. It seems the wee shrimp-like fellows didn’t get the memo. Instead they got an all you can eat coupon to a fine seafood buffet.
