Here is information on the 2021 Northwestern Cell Friends of the Pleistocene, Glacial Lake Missoula, September 9-12, 2021 [PDF] at Paradise Center Montana. For more information or questions contact Larry at lsmith@mtech.edu.

Research Interests

Most of my work centers on stratigraphy, sedimentology, Quaternary geology, subsurface and surface geologic mapping, and petroleum geology.

Projects include:

The depositional history of Glacial Lake Missoula and features formed during multiple drainage events of the lake. Glacial Lake Missoula has been of great interest in western Montana for 100 years. I have ongoing interest in geological mapping, sedimentology, and stratigraphy of glacial deposits in the Clark Fork River drainage basin to improve understanding and correlation of these deposits. I led a 2021 Friends of the Pleistocene (Pacific Northwest Cell) field trip to part of the Glacial Lake Missoula features. The field guide can be downloaded here.

Education

Ph.D., Geology, University of New Mexico, 1988
M.S., Geology, University of New Mexico, 1983
B.S., Earth Science, Geology, University of California, Santa Cruz, 1977

Non-Research Academic Interets

I enjoy teaching introductory and field-based geology classes. I find air-photo interpretation, photogrammetry, and all aspects of map-making interesting and important. My graduate students need to learn GIS in order to produce maps for their projects and theses.

Personal Interests

Most of my interests are in outdoors activity - hiking, cross country and telemark skiing, cycling, in the great outdoors of the Northern Rocky Mountains. In the winters I enjoy playing and refereeing ice hockey, and working in my woodshop when I get a chance.

Another passion is historic preservation in our area, and of my own 1890 house in particular. I teach historic brick preservation classes each summer and serve on the board of Butte Citizens for Preservation and Revitalization.
