the magma never reached the surface. It was the superheated groundwater that produced the eruptions. Then, the Mono flow created the ryolite-composed eruptions in the area? How did the volcanic glass or obsidian form? Was that after the magna had been exposed to the surface, and then slowly cooled???
Geez, there must have been quite a few separate eruptions in the area! Nice page, I have to go check it out myself! - Larry
only at the two southernmost Inyo Craters did the magma never reach the surface. Those two craters were blasted out by the superheated water. At all the other described domes there were magmatic eruptions. You are correct, there were many separate eruptive series over the millenia.
