Cathedral Formation, Geological formation in Alberta and British Columbia, Canada.
The Cathedral Formation extends approximately 100 kilometers through Yoho National Park, featuring thick sequences of carbonate rocks and prominent limestone cliffs.
Charles Doolittle Walcott named this formation after Cathedral Mountain while conducting research that led to the discovery of Burgess Shale fossils.
Geologists and researchers frequently visit the formation to study its preserved marine fossils, including trilobites and stromatolites from the Middle Cambrian period.
The formation contains substantial deposits of magnesite at Mount Brussilof, which has been extracted through open-pit mining operations since 1982.
The Cathedral Escarpment rises between 100 to 300 meters, marking the edge of an ancient carbonate platform where prehistoric mudflows preserved numerous organisms.
