A couple sleeping in their car in the parking lot were awakened at about that time by what they thought was an erathquake. Frightened, they drove south. They realized their mistake when they saw the large steam cloud from while driveing through Elk Park. Apparently they thought there was an earthquake and hurriedly left the area. By the time they got to Elk Park they either came to their senses or saw water, and returned.
Reports are they do have photos of it in water phase.
At 11 the steam was still heard from the interchange. At 11 Cistern was about 3 inches below overflow. No later data about Cistern. As of 8 days ago, nearly all minor activity was from the south vent, with occasional norths - similar to last year's mode of activity. Today, visitors told NPS staffers that on Saturday and Sunday they saw water 40 to 60 feet high from both vents.
