Walcott Quarry, Fossil quarry in Yoho National Park, British Columbia, Canada.
Walcott Quarry is located in a high mountain area between Wapta Mountain and Mount Field and contains millions of fossils from the Burgess Shale, a world-famous rock formation. The fossils date to the Cambrian period and display marine organisms that died over 500 million years ago and became preserved in shale layers.
Naturalist Charles Walcott discovered the quarry in 1909 while exploring the mountain region. His systematic excavations between 1911 and 1913 uncovered over 65,000 fossils and made the location one of North America's most important paleontological sites.
This site forms part of a UNESCO World Heritage Site and shows some of the oldest known marine life from over 500 million years ago. Visitors can see how fossils are embedded in the rock layers and understand why this location holds global scientific importance.
Reaching the quarry requires a demanding hike of about 22 kilometers with significant elevation changes, so visitors should start early in the morning and bring good stamina. Certified guides lead groups along this route and explain the geology and fossils along the way.
What makes this location special is that the mountain shape of the nearby Cathedral Escarpment created conditions to preserve soft bodies of sea creatures perfectly, which is rare for fossils. This preservation gives insights into organisms that normally do not fossilize elsewhere.
