Cracker Creek cone, the hill in the center of the above photograph taken
looking to the east, is a small cinder cone at the head of Cracker Creek,
immediately east of Ruby Mountain volcano.
A large lava flow that partly filled Ruby Creek may have originated from
this cone. The lower west side of the cone appears to be partly covered
by glacial till, suggesting that the cone is older than the most recent
glacial advances down Ruby Creek. Cracker Creek cone, part of the northern
Cordilleran volcanic province (Edwards & Russell 2000), is one of three
young volcanoes in the Atlin area. The other two are Ruby
Mountain volcano and Volcanic Creek cone.
