Published since 1964, The Mountain Geologist is the peer-reviewed, quarterly journal of the Rocky Mountain Association of Geologists (RMAG). Issues are published online in January, April, July and October of each year. The Mountain Geologist circulates to the 2200-plus members of the RMAG and about 200 university and government libraries and industrial associates.

The Mountain Geologist is a regionally oriented publication. It focuses on the geology of the Rocky Mountains area of the United States. Topics from outside the region are of interest to the readership when they bear on problems relating to those in Rocky Mountains geology. The range of topics presented in The Mountain Geologist covers almost every sub-discipline in the geosciences: environmental geology and geomorphology, geochemistry, geophysics, hydrogeology, mining and petroleum geology, paleontology, petrology, stratigraphy, structural geology, and more. Authors are from industry, government, and academia.
