Geologic Grandeur

Glacier National Park- Highline Trail – Adam Pate

For millions of years, ancient seabeds were twisted, folded, and lifted by the tectonic crush of Pacific and North American plates. Successive ice ages then plowed through relatively soft limestone layers to carve river valleys, leaving behind dark forests and deep pockets of fresh water that endure today as glaciated lakes. The prairie meets the mountains at dramatic escarpments along the Rocky Mountain Front where ranchers and conservationists have joined to protect vast expanses for restored populations of wildlife. Weather systems converge over these mountains—Pacific, arctic and continental—magnifying the value of many geologic niches for a great variety of plants and animals.
