GEOLOGIC BACKGROUND:
The Devils Garden lava field consists of several flows of
pahoehoe lava that erupted from fissure vents in the northeast
part of the Devils Garden. The main vent on the north end of the
fissure fed two large gutter/tube systems. Several small vents
to the south produced The Blowouts (two large spatter cones),
several small spatter cones, and flows. Several older hills
and higher areas were completely surrounded by the flows
to form kipukas. The distal ends of the flows show excellent
examples of inflated lava.
