Nature
Coffee Crater is a Holocene basaltic cinder cone in northwestern British Columbia's Mount Edziza Provincial Park, at the southern end of the Big Raven Plateau within the Snowshoe Lava Field and larger Mount Edziza volcanic complex. Rising to about 2,000 metres, it has a summit crater formed by eruptions of lava and tephra. Its most distinctive feature is a southwest-flowing lava flow that ponded against stagnant ice and partly rode over it; when the ice melted, the lava collapsed and left an escarpment about 18 metres high. The exposed face preserves pillows, radial columnar jointing, and minor tuff breccia, showing an unusual interaction between lava and ice.
