My field work in the Gravelly Range of southwest Montana has been on-going for a few years. Each field season there usually are field crews from the Alf Museum/Webb Schools headed up by Don Lofgren, along with many other earth scientists from a variety of places working together in the Gravelly Range. We base our…

This issue contains papers in honor of James Gilbert Honey, a paleontologist and stratigrapher who focused on the Cenozoic, particularly…
Working On High Elevation Tertiary Strata, Southwestern Montana
Working on Tertiary strata in the Gravelly Range, southwestern Montana, is sometime daunting to do. The Lion Mountain Tertiary section shown in the photo to the right is one of those places that makes for a grueling day or several days of field work. The Tertiary section unconformably overlies various Paleozoic units, such as Mississippian…
Greater Yellowstone Area Eocene to Recent Hydrothermal Springs
Geologic field work is always fun, but especially so when it turns up something unexpected. Working on Eocene to Recent geology and vertebrate paleontology in the Gravelly Range, southwestern Montana promised to be enthralling because the volcanics, sedimentary units, and vertebrate fossils are at elevations of about 9,000 feet. But to come across extensive, unmapped…
