Geology and Geographic Location of Popular US and Canadian Climbing Areas. Canada. Unknown Frontier.
Most of Canada has not been explored for climbing. Some routes and “spots” do exist but not as plentiful as USA. Some places are very remote and require guides both native and conventional mountain guides to get to plus a lot of back- country knowledge.
Almost all of the rock formations in Canada are from glacial influence with some, more towards the eastern shore, are eroded by sea water and wind.
Minnesota is the only state where you can find every type of rock available to climbers that are present at mainstream climbing areas. Professional climbers from all over come to MN to train because of the variety of rock available to them at such short distances. Minnesota is viewed in the climbing community as the geologic and geographical “oddity” of America.
As a general view of North America most climbing areas have been effected by glacial activity while the stragglers being wind and water erosion. Geographically you can place glaciers at every point where rock formations are especially in the northern areas. There are also similarities in rock type from Canada to the US. On the human aspect most climbers tend to live close to their favorite climbing area or rock type.
