“A classic geyser basin trail among some of the most interesting thermal features in the park.”— Tom Carter
The first significant feature along the trail is Giantess Geyser, one of the largest and most powerful geysers in the world. Its infrequent eruptions explode unpredictably from its large pool to a height of 200 feet, 2 to 6 times a year. Its duration lasts many hours and progresses from a water phase to a powerful steam phase. During eruptions, the seismograph in the visitor center can detect small tremors in the ground and the roar of the steam can be heard more than a mile away. The Washburn Expedition, who named this magnificent feature, exclaimed, "All we had previously witnessed seemed tame in comparison."
The trail continues past beautiful Doublet Pool (on the left), Aurum Geyser (on the right), the Observation Point Spur trail to Solitary Geyser (on the right) and Ear Spring (left, see the resemblance?) before reaching a junction in the boardwalk. Turn left and immediately view the Lion Group geysers on the right. The Lion Group consists of four geysers: Lion, Lioness, Big Cub, and Little Cub, which are all connected underground.
Of these, Lion has the largest cone and eruptions. Active phases normally occur each day. Eruptions of Lion Geyser last 1-7 minutes and are often preceded by sudden gushes of steam and a deep roaring sound, hence the name Lion. Just past the Lion Group lies Heart Spring, named by park geologist, George Marler, because its shape resembles a human heart.
The last important feature on Geyser Hill is Beehive Geyser, a classic cone-type geyser that erupts in a steady column of water through a small vent or geyserite cone. Eruptions usually occur twice each day with displays lasting 4-5 minutes. During an eruption, the narrow cone acts like a nozzle, projecting the water column to heights of 130-190 feet. Shortly past Beehive the trail concludes its loop of Geyser Hill.
