lots of drama here. Geologists estimate that the Hell's Acre Lava Field was created about 3250 BC. The lava field was created by the Lava Ridge-Hell's Half Acre fissure vent, and marks the southern edge of this area of volcanic activity. One scientific team hypothesized that the seven lava fields in the vicinity of Hell's Half Acre may belong to as few as two fissure vents.
Volcanism attributed to the hotspot began approximately 15 million years ago in the western portion of the Plain, with lava fields becoming younger to the east. With lavas erupted approximately 4,100 years ago, Hell’s Half Acre is one of the youngest lava fields. This pattern—older lavas in the west and younger lavas in the east—reveals the direction the plate was moving.
