Geyser Basin

Please read the WARNING about traveling safely in backcountry thermal areas.

Lone Star Geyser Basin can be reached by various routes but the shortest and most enjoyable is by hiking or biking along the trail that follows the Firehole River. This trail follows an old road bed that used to take car traffic to Lone Star Geyser. The road has been closed for decades now.

The trailhead for this trail, the Lone Star trailhead, is just upstream from Kepler Cascades on the road from Old Faithful to West Thumb. About 3.5 miles southwest of Old Faithful. See a trail map. Once you are away from the main park road this is a very nice hike or bike ride. This is one of the few trails open to bicycles in the park. The two and one half mile trail to Lone Star is quite flat, easy and passes through pretty scenery.

Buried Geyser: [Warning] [Pictures]

[Buried Geyser Description provided by William P. Moats.]

Buried Geyser has both frequent and powerful eruptions. However, in spite of such notable activity, it has been largely ignored by geyser gazers. Buried Geyser lies near the base of a hill about 1/2 mile east-southeast of Lone Star Geyser , on the south side of the Firehole River. With no trail leading to it, Buried Geyser can be accessed by fording the river near Lone Star, or by crossing the river on the Shoshone Lake Trail bridge about 1/2 mile west of Lone Star, then backtracking.

Situated at the upper end of a narrow barren drainage, Buried Geyser is easy to locate because of its frequent activity and the steam from its eruptions. Those planning a visit and having a Global Positioning Satellite (GPS) receiver can travel to it by hiking to the following latitude/longitude: 44 degrees 24.92 minutes North, 110 degrees 48.06 minutes West.

Buried Geyser was recognized as a perpetual spouter in 1973, and has been known to have periodic or true geyser activity since 1983. Only one short dormant period has been
