There are a small number of small geysers and springs located along the trail around Old Faithful.

Bison Skull in Blue Star Spring

A Bison Skull in Blue Star Spring. This unfortunate juvenile fell into the Blue Star during the Winter of 1996-97. He was quickly killed by the hot water. For a period after this incident, the pool smelled like beef soup.

Blue Star is a pretty Blue Pool that is usually near to boiling temperature. Because it is so close to Old Faithful it is very easy to see. Thus, not only is it popular but it has also been the subject of abuse as tourists throw trash into the pool.

Chinese Spring: [Map]

Chinese Spring rarely erupts. Most eruptions have been induced. The story is that in the early days of the park a concession was using the spring for hot water to wash clothes. The spring erupted as a geyser scattering clothes in all directions. The story is that the proprietors were Chinese, or at least Asian, hence the name. A few years ago, the name was changes from Chinaman Spring to Chinese Spring because the former name was deemed inappropriate.

Chinese Spring erupts to about 20 feet for a duration of about 2 minutes.

Geyser Hill: - Map [Picture]

There are over 40 geysers on geyser hill. Two of these, Giantess and Beehive are among the largest in Yellowstone, and thus, the world. While you will need considerable luck to see Giantess, Beehive has been fairly easy to see for about the last decade. Even if you don't see either of these two large geysers erupt, Geyser Hill is worth exploring. There are many other geysers to see along the boardwalk on the "hill" along with pretty pools and interesting sinter formations.

[Anemone Geyser Description provided by Steve Gryc.]

Anemone Geyser's frequent eruptions should make this feature one of your first stops as you walk around Geyser Hill. Anemone has two vents. (There was a third vent but it is now filled with gravel and can't be seen). The vent closest to the boardwalk is the larger of the two and is informally referred to as "Big" or "North" Anemone. The vent is a round, shallow, funnel-shaped crater delicately colored with pastel pink, orange, and yellow. The spiny sinter deposits in the crater may have reminded the namer of this geyser of a sea anemone, though the round shape and colors remind this writer of the anemone flower. The larger vent gives rise to the larger eruption, though its eruptions are most often much briefer than those from the smaller vent. You can hear the water rise in Big Anemone before it quickly fills the crater and begins its bursting action. The eruption is brief, usually between 25 and 45 seconds, and quickly builds to a maximum height of about 6 to 8 feet. After the eruption the water quickly drains from sight, often with an amusing sucking or gurgling sound. Intervals between eruptions average between 6 and 10 minutes, though long eruptions from the smaller vent often have the effect of lengthening this interval.
