|We got up and out on the trail early, so that it wasn't so hot. The Butterfly Trail was a 2 mile moderate hike. It had some steep slopes, steps and uneven surfaces. Winding along the west side of the Petrified Dunes. When we got near the top, there was a lava tube. Harrison went down in to check it out. He said it went for a long ways and was no problem for him to stand up in it. Very dark though, even with his head lamp. There was a nice overlook of the West Canyon. A perfect morning. We are going to the Petrified Dunes next.
