Crystal Geyser is a cold water geyser near Green River. Due to
it's unpredictability, it can be an exercise in patience. It
can go off anywhere between every hour to 24+ hours! Even if
you don't get lucky enough to see it erupting, it is an
interesting place to visit.
When dry, the trailhead is reachable in any vehicle.
To get there, take the east Green River exit (exit 164). Go
south, then east (left) onto the frontage road that parallels
the highway. After 2.2 miles, turn south (right) and continue
3.5 more miles where a junction is encountered. Go right, and
travel about 0.5 miles to the geyser. In summer of 2007, this
was well signed.

The geyser is a large flat area with a pipe sticking out.
Eruptions of the geyser have created a large amount of yellow
flow stone as the water drains down to the Green River a short
distance away. It follows common sense, but please do
not put anything down the pipe of try and approach the pipe
during an eruption.
Eruptions occur at unpredictable intervals, and for
unpredictable lengths. If you want to see an eruption, the best
plan is to camp near the geyser. Although camping is not great,
it is certainly possible. The noise when it erupts is enough to
wake all but the deepest sleepers.
