Alligator Lake in southern Yukon, Canada, is a group of basaltic cones and lava flows (the Miles Canyon basalts). It is located at the northern extremity of the Stikine volcanic belt, 30 km southwest of the capital city Whitehorse.
The field contains 2 cinder cones on top of a small basaltic shield volcano which is eroded by glacial cover. The cones probably post-date the ice age and seem to be a few thousands years old. Lava flows from both cones traveled to the north and were erupted simultaneously. The longest lava flow extends 6 km N and reaches a width of 10 km.
