Description: From Jicha and Singer (2006): "An older, tundra-covered 0.08 km cubed rhyolite flow (rcv) crops out to the west of the rcc cone. This plagioclase-phyric lava dips 20 degrees to the northwest and is strongly flow banded with alternating layers of red rubble and black, glassy rhyolite. Three incremental-heating experiments from the glassy rhyolite yielded a weighted mean plateau age of 7.5+/-2.0 ka (Table 1; Fig. 5 [in original text])."
