NotesAs the originated magma was being forced up, it cracked the rock allowing radio lines of vents to be formed. Each of the vents are producing yellow sulfur around them. These are little vents, and are what would be called pressure cracks. As the lava came up through that throat, it would kind of force the volcano itself to split in cracks. Gases would come out these cracks, giving the yellow deposits which you can see along them. This would obviously be the sulfur systems. Fortunately for us, they were not sulfur, but these new minerals that we had totally misdiagnosed and were discovered by undergraduate students.
