Global Volcanism Program | Image GVP-03055
The lava flow in the foreground, with snow-capped Mount Jefferson in the background, was emplaced about 2,600-2,900 years ago from Yapoah scoria cone on the north flank of North Sister. Lava flows in the middle of the photo originated from the Little Belknap shield volcano, part of one of the largest concentrations of recent volcanism in the continental United States: the McKenzie Pass area of the central Oregon Cascade Range.
