The
huge Brewster snowmobiles that take tourists up a near-vertical
grade to the top of Athabasca Glacier near Banff, Alberta, were designed
especially for their unique job. Carrying fifty passengers at a time,
the Brewsters make it possible for anyone to experience a glacier, no
ice axe necessary!
The Columbia Icefield is located on the boundary
of Banff and Jasper National Parks. One of the largest accumulations
of ice and snow south of the Arctic Circle, it covers an area of nearly
150 square miles. The Athabasca Glacier is one of eight major glaciers
fed by the Columbia Icefield, whose runoff also feeds streams and rivers
emptying into the Arctic, Atlantic, and Pacific oceans.
The Athabasca Glacier is a wedge of ice about
four miles long and half a mile wide, and the Brewster "Ice Age
Adventure" tour takes visitors nearly two miles up the slope in
a "Snocoach." The driver explains how glaciers are formed
and points out interesting geological features, and visitors have a
chance to walk around on the glacier's surface at the icefall below
the glacier headwall.
