First, if you can’t get a reservation in time to visit Lehman Caves, just visit the park anyway. I took the virtual cave tour, and, I suspect that Timpanogos in Utah is better and less damaged. Besides, the park isn’t a cave park, it’s the highlight of the Great Basin area, which includes most of Nevada, western Utah and parts of three other states, and has a glacial basin of its own at the top of a 13,500 foot mountain.

Second, stop at Mather Overlook to admire the views and fall foliage of yellow and orange Aspen amid the dark green conifers. There’s a bronze model there that shows the structure of the basin, which is helpful orientation, since it is a long winding road.

Third, understand that the glacier here, “the only glacier in Nevada”, is gone. In theory, there might be some subterranean ice under some of the rocks for another couple years, but climate change has wiped this glacier off the face of the earth. The park maps showing a “rock glacier” in white are out of date. Any snow you see up there is seasonal.

Fourth, take the Glacier Trail anyway, since it goes through the Bristlecone Pine grove and up into the basin. If you only get as far as the grove (2.8 miles roundtrip), that’s what I felt was the highlight of the park. The other two Bristlecone Pine groves are in very remote areas of the park. There are also some trails to pretty alpine lakes, but be careful, as many of the hikes are over 10,000 feet. Spending the night at altitude can help, as well as give you lovely views of the Milky Way.

Finally, this is my favorite park for old trees. The Bristlecone Pine, far from merely eking out a bleak minimal survival, is a gold resinous Adonis, shining in the bright Alpine sun, with luxurious thickly packed bright green bristles. We don’t know how long they can live. One that was removed from here in 1964 was over 4,900 years old. Unfortunately, climate change will likely make them extinct, as other trees will grow at higher elevations, crowding them and subjecting them to more wildfire damage.
