Hillman Peak – Prominent Geological Features of Crater Lake National Park
Hillman Peak is the highest point on the rim, at 8,156 feet elevation. Hillman Peak was formed as a parasitic cone when a vent opened on the side of Mount Mazama. The collapse of the parent peak cut Hillman in half, exposing its inner structure. Its spires are ancient feeder tubes for the lava that built the cone and were decomposed and tinted yellowish-orange by the gases and other hot liquids that rose through them.
