I just got back from a long hike in Rocky Mountain National Park outside of Estes Park, CO. Most of the hike was above treeline. We spotted a heard of elk and a local with whom I was hiking told me the elk were up there because the area had some late rain; normally that tundra is all brown by July. In the late 80s and early 90s I hiked that area every summer. I don't recall the tundra grass ever brown in July.
