Bear Den Geyser is one that is sorely missed. It was a very unique geyser, erupting out of a hole surrounded by rounded boulders of rhyolite. The vent looked like a bear's den, hence the name. It erupted in a series of bursts , sometimes up to 14 separate eruptions.They leaped out of the vent at an angle,preceded by a roar of steam.The sound of the steam then water was "whoomp....shhhh" It was erupting in the early 80's then went dormant and during the dormant spell, the rhyolite boulders collapsed and blocked the vent completely. Located at Norris Geyser Basin...

A pretty bad photograph owing to bad lighting conditions. The photo is only notable because Gibbon Hill Geyser no longer exists.It was completely buried by mudslides after the 1988 fires removed the trees and other foliage from the slope above it and made the hillside susceptible to erosion and slides. It's too bad, because it had wonderful beaded geyserite formations, and entertaining eruptions.Located in the Gibbon Hill Geyser Basin.

A shot taken in January 1983, in the bitter cold of Yellowstone winter.You can see here that Daisy is a cone type geyser, something that's not as obvious from back at the distance of the boardwalk.
