Detailed Description

The 1940 cinder-and-spatter cone as seen from the caldera floor looking to the southeast. This cone, which is about 114 m (373 feet) high, was built around the vent as lava spewed from it over a period of 134 days. The dark-colored pāhoehoe flows visible in the foreground were erupted in 1984. Rocky debris on top of the 1984 flows is from small collapses of the steep caldera walls. The largest boulder is about 1 m (3 feet) long.
