Geothermal gradients in the Missoula and Bitterroot Valleys, west-central Montana
Robert B. Leonard, Wayne A. Wood
1980, Water-Resources Investigations Report 80-89
Temperature-depth profiles of six cased test holes in the Missoula and Bitterroot Valleys, west-central Montana, consist of linear segments, the intersections of which commonly correspond with lithologic boundaries. Geothermal gradients commonly decreased with depth, probably as a result of compaction and higher quartz content of the deeper sedimentary deposits. There...
