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.
Inquiries regarding suitability of topics should be sent to Joyce Trygstad Nelson, Executive Editor (email@example.com) or by calling the RMAG office at 303-573-8621.
Authors should submit manuscripts electronically to firstname.lastname@example.org. Please indicate topic in the Subject line. Manuscripts should be written in accordance with the RMAG “Author Style Guide."
