Tucson--Bozeman

Our flight left Tucson at 6 a.m.!! Everyone got to the airport on time and we made the plane. David Trilling included a guide to aerial geology, but we were clouded out until Salt Lake City. It cleared up later though, and the Salt Lake-Bozeman leg showed us the Tetons and Yellowstone Lake.

We picked up extra camping gear and were on our way to the park, when Barb got pulled over by a small-town cop. She and Jay acted appropriately chagrined and escaped getting a ticket.

We made it into Yellowstone Park with a few minutes of daylight to go. Not wanting to waste any, we stopped to look at a rhyolite flow. Here, David tries to determing mineralogy by the age-old geologists' test of licking the rock.
