Cocoa Crater is a part of the Mount Edziza volcanic complex, which consists of diverse landforms such as shield volcanoes, stratovolcanoes, lava domes and cinder cones.

The cone contains a volcanic crater and was the source of a 2 km (1.2 mi) wide lava flow that travelled northwest on the Big Raven Plateau into the upper portion of Sezill Creek canyon.

[2][7] In his 1992 report The Late Cenozoic Mount Edziza Volcanic Complex, British Columbia, Canadian volcanologist Jack Souther gave Cocoa Crater the numeronym SLF-10, SLF being an acronym for the Snowshoe Lava Field.

[9] Cocoa Crater is located in Cassiar Land District of northwestern British Columbia, Canada, immediately southwest of Mount Edziza at the southern end of the Big Raven Plateau.

[1][6][11] The volcanic complex consists of a group of overlapping shield volcanoes, stratovolcanoes, lava domes and cinder cones that have formed over the last 7.5 million years.

[18] Cocoa Crater is a hawaiitic cinder cone of the Big Raven Formation, the youngest stratigraphic unit of the Mount Edziza volcanic complex.

[4][6] A 2 km (1.2 mi) wide lava flow from the cone travelled to the northwest, spread across the Big Raven Plateau and entered the upper portion of Sezill Creek canyon.
