Lone Star Geyser

Lone Star Geyser is a cone geyser in Yellowstone National Park that rises from the ground to a modest height. During eruptions, hot water and steam shoot upward in regular cycles throughout the day.

Railroad surveyors working for the Northern Pacific discovered this geyser in 1882 while exploring the Upper Geyser Basin. The name emerged from these early encounters with the landform.

Visitors keep a shared log book near the geyser where they note eruption times for others to see. This simple record creates a sense of community among travelers waiting to witness the natural display.

The geyser sits at the end of a hiking trail that begins from the Kepler Cascades parking area and covers several kilometers round trip. Wear comfortable hiking shoes and bring water, as the trail has limited shade along the way.

Water and steam follow a predictable rhythm that allows visitors to plan their arrival times. This dependable pattern makes it one of the most accessible geysers to visit in the park.
