Horseshoe Canyon Formation, Geological formation in Drumheller, Alberta, Canada
Horseshoe Canyon Formation is a layered geological structure in the Drumheller area stretching over 250 meters deep. It contains mudstone, sandstone, and coal seams positioned near the Red Deer River Valley.
The formation originated during the Late Cretaceous period roughly 70 million years ago, spanning the Campanian to early Maastrichtian stages. This era shaped the deposits that later became important for mining activity.
The formation holds deep meaning in Alberta's mining heritage, with local communities connecting its layers to coal extraction and the lives of earlier generations.
The formation is accessible through observation areas along nearby highways, with several points offering clear views of the geological layers. Wear appropriate footwear as the terrain is uneven and weather protection may be needed.
The layers preserve an extensive collection of dinosaur fossils, including finds of Albertavenator and Albertosaurus. Paleontologists continue discovering new species within these deposits.
