Global Volcanism Program | Image GVP-03077

The lava flow across the upper part of the photo, seen here from Black Crater, originated from Yapoah cone on the north flank of North Sister about 2,600-2,900 years ago. The flow traveled 5 km N before being diverted by lavas from Little Belknap shield volcano and flowing an additional 8 km NE. Photo by Lee Siebert, 1995 (Smithsonian Institution).
