Science and the Wilderness
Topic: Science Workplace

Well this entry is coming to you from the
Samesun Backpackers Lodge in Banff.
Just came back from a hike to the Hoodoos (
see image right), formed by the petrification of loose soil by limestone. As the cliff eroded over the centuries, loose soil melted away leaving behind these strange
Giacometti figurines.
The Canadian Rockies are truly spectacular. Pushed skywards by the collision of the North American plate with the plate covering the Pacific ocean floor, the Rockies around Banff and Jasper were once shallow ocean beds themselves. Hiking up Tunnel mountain and Sulfur mountain, I found plenty of
fossilized corral and other remnants of an ancient corral reef. Further west in
Yoho National Park lies the famous fossils of the
Burgess Shale.

Many incredible lakes are located in the mountains such as
Lake Louise (
left). Their strange turquoise-blue color, is the result of the glaciers that ffed them. I'm not sure what specifically gives the water it's vivid color but it has something to do with the "rock flour" found in glacial meltwater -
if anyone out there knows, send me some info, thanks.
Since there is much compression in the North American tectonic plate around Banff, there are places where magma gets relatively close to the surface, super-heating parts of the water table. This hot water then dissolves minerals trapped in the sedimentary rock, such as sulfur or radium, and then due to elevated pressure rises to the surface. These "hot-springs" are then populated by tourists ... some looking for the fountain of youth ... I guess.

In fact workers of the Canadian Pacific Railroad discovered a sulfur-spring (
see image right). To mediate the ownership dispute between several workers, CP Rail (a Canadian Government Corporation) bought out all of the parties, built a fantastic resort,
the Banff Springs Hotel and created this giant National Park (i.e.
Banff). Unfortunately some of the springs are inhabited by an endangered species of snail that feed off of algal mats (the brown floating islands in the picture on the right) and are sensitive to cosmetics worn by the would be human bathers. As a results many hotsprings are no longer open for bathing, but can be visited.
