Photos by C. Dennis Lathem.

September 2005 The Grand Tetons and Yellowstone. Many of these photographs were taken on a special tour of Yellowstone conducted by the Park Geologist. This was one of the field trips from the recent Interstate Oil & Gas Compact Commission meeting. It was an amazing trip and for a non-geologist I learned a lot. It did not hurt to literally be surrounded by Geologist from all over the United States.

Thanks to Ronald Surdam, Director of the Wyoming State Geological Survey for making this field trip possible!
