Details for: Belknap
The McKenzie Pass area in the central Oregon Cascades contains one of the largest concentrations of youthful volcanism in the United States. Belknap shield volcano, seen here from Black Crater to the SE, is capped by a snow-covered pyroclastic cone. Lava flows from Belknap and the smaller Little Belknap shield volcano in front of it cover nearly 100 sq km. Most of the largely unvegetated flows were erupted between about 2900 and 1500 years ago.
