Crowsnest Formation, Volcanic rock formation in southwestern Alberta, Canada
The Crowsnest Formation is a volcanic rock formation in southwestern Alberta stretching along the Front Ranges of the southern Canadian Rockies. The rock displays distinctive structures from ancient volcanic activity and is visible throughout the region.
The formation was created by explosive volcanic eruptions during the Early Cretaceous period roughly 100 million years ago. These eruptions shaped the rock structures visible in this region today.
Geologists and researchers regularly visit the formation to study its rare mineral composition, including melanite, analcime, and the uncommon blairmorite.
The rock formation is accessible from Highway 3 near Coleman and can be viewed from various vantage points in the region. The best time to visit is during warmer months when trails are easy to walk.
The rock contains rare minerals and crystal combinations found in only one other location worldwide in Africa. This makes the area particularly interesting for mineral collectors and geology enthusiasts.
