The Cracker Creek cone is a small cinder cone in the Surprise Lake volcanic field, located about 27 km east of the town of Atlin, British Columbia. It consists of a pile of scoriaceous lapilli that has been modified slightly by glaciers. Its age is not known. A nearby lava flow, the Ruby Creek lava flow, is the largest in the Surprise Lake volcanic field. It extends for at least 3 km along Ruby Creek, and is locally up to 30 m thick. Potassium-argon dating indicates the age of this flow to be about 540 ± 200 thousand years old; its source is unclear, due to poor exposure, but it probably originated from either the Cracker Creek cone or nearby Ruby Mountain.
