Alligator Lake volcanic complex

The Alligator Lake volcanic complex is a group of basaltic cinder cones and lava flows in south central Yukon. The upper part of the Alligator Lake volcanic complex consists of two well-preserved cinder cones capping a small shield volcano. They probably post-date the local Holocene glaciation. Lava flows from both cinder cones traveled to the north and were erupted simultaneously. Their compositions range from alkali olivine basalt to basanitic. Lava flows from the northeast cone are the largest extending 6 km (4 mi) from the cone and expanding to a width of 10 km (6 mi) at the terminus.[1]
