The most famous things in Lehman Cave are the discs. They occur in all sorts of positions and are created when water is ejected under pressure. There are always two discs that grow at the same rate, separated by a very thin crack where the water comes out. The water that manages to get out of the disc will create draperies, popcorn or other growths on the outside of the discs. At times one of the discs will fall off the ceiling. No one knows why Lehman Cave has so many discs.

Thursday morning we woke up very early to drive up the road to Wheeler Peak to walk to the bristlecone pine forest and to avoid the wind. On the way we passed through different vegetation levels, including juniper, pinon pine, Douglas Fir, curly leaf mahogony, Lehman Pine, spruce, etc. We also passed the Osceola Ditch, an 18-mile long flume to divert water from Lehman Creek on the east side of the park to the mines of Osceola on the west side where they engaged in placer mining. The tiny glacier on Wheeler Peak is the southernmost glacier in North America and consists mainly of ice frozen in the rock debris, which when it melts lubricates the rocks which move like a glacier.
We hiked to the bristlecone pine forest at timberline. On the trail we met a BYU biologist who was studying flies during a bioblitz organized by the park over three days. The ranges in the basin and range area are like islands and species remain and develop in isolated islands because they cannot cross the desert. It is for this reason that there are no bears in Great Basin N.P.

Bristlecone Pines are the oldest living creatures on the planet. They regularly live more than 3,000 years and survive by only keeping small portions of the tree alive. In this photo there are two strips of bark that are feeding those few branches that have bristles. The wood is extremely dense and resinous and is polished by the wind and the snow. Adversity seems to make them thrive and their needles can last more than 40 years.
This bristlecone pine has been dated by core samples at more than 3,200 years old. They are truly majestic things.
We headed east around 10:30 a.m. across Utah 21 through completely desolate territory until we hit Beaver on I-15. From there we took I-70 to Green River, where we camped for the night. This is a view from a roadside overlook on I-70 into the red rock canyon areas in southeastern Utah.
