Summary

Album caption and index card: Brecciated rhyolite lava flows along the Firehole Canyon drive. As a lava flow moves outward from its center of eruption, a chilled crust develops along its upper surface and outer edges because of the cooler temperatures in those parts of the flow. Continued movement of the still-molten rock in the interior of the flow causes this crust to break up (brecciate) into angular blocks. The blocks are then tumbled along until the whole mass finally solidifies. Yellowstone National Park, Wyoming. 1970. Published as Figure 31 in U.S. Geological Survey. Bulletin 1347. 1971.
