40 DEGREES OF LATITUDE
The Rocky Mountains, vast yet quietly humbling, define this part of the world. Vertically, they soar above 14,440 feet(4,401 m). Spanning 40 degrees of latitude, some 4,800 kilometres((2,980 mi), they run the length of North America from Liard Plain in BC's north to the Rio Grande in New Mexico. The mountains you see north of the Liard river, into the Yukon, are often grouped in with the Rockies, but are actually part of the Mackenzie Mountain system. The river systems that gather and wind their way out of these mountains head in all directions. 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 Okanagan Highlands is an area centred in the Interior of British Columbia, but the term is used in a slightly misleading fashion to describe an arc of Eocene lakebed sites that extend from Smithers in the north, down to the fossil site of Republic Washington. 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
Waterfront Property fetches a high price today, even in this economy. Investing early is clearly the way to go. We've all heard tales of folk who bought up acreage in the early days for pennies and much to their delight, the bit of land they chose is now worth millions.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, one of the northern Gulf Islands on the west coast of British Columbia, draws me back year upon year. Both for its picture perfect sunny days, stormy seas and the island's own rugged beauty. 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.
