Desert Cone – Prominent Geological Features of Crater Lake National Park
#6 on the map – northwest of Crater Lake and west of the North Entrance Road.
This scoria cone is located in the north-central portion of Crater Lake National Park, Oregon.Most of this cone consists of vesicular, red-crusted dark scoria and fine ash. Bombs up to 4 feet in length are not uncommon, and many have the spindle, almond, and spiral shapes typical of lava clots blown out in a viscous condition, the form being modified in flight. Short flows of lava oozed through the scoria near the summit, and probably others account for the spurs on the sides of the cone ….
