Our previous visit to Great Basin NP was 6 years ago, and at that time the trail to the Bristlecone Pines on Mt. Wheeler was covered with 3-4 feet of snow. This time it was mostly clear, but that actually meant it was harder to wander around the grove once we got to it. There is a very nice interpretive trail, but if you want to get near any trees not along the trail, it is a major job of crossing the field of angular boulders to get to them!
