Anemone Geyser, #07229

Anemone Geyser, showing the dry vent between eruptions, is located along the Geyser Hill trail in the Upper Geyser Basin, a few hundred yards from Old Faithful. Nearby is Little Anemone Geyser, a bit further off the Geyser Hill trail. Big and Little Anemone Geyser's are two vents of the same geyser plumbing but typically erupt independently Anemone Geyser's eruption, although small in height (10 feet (3m)) with a short duration (about a minute), occurs with a short average interval (about 10 minutes) and offers a view of a “typical geyser eruption”. Initially, water rises in the subterranean passages, reaching the vent and soon overflowing the geyser opening. Then the geyser erupts, throwing liquid water and steam into the air. As steam is exuded and the pressure inside the geyser vent reduced, the eruption slows and stops. Steam inside the geyser transforms back to water, sucking the pool of water in the geyser's opening back down the vent.
