Investigations Concerning Bentonite Deposits Near Ramsay, Montana

The purpose of Part I of this report is to determine the origin of the bentonite deposits, also to locate them with reference to section corners in the vicinity and to determine their extent. The field work for this report was done in the fall of 1933 and during the spring of 1934. The roads, geologic contacts, and culture in general were mapped with the use of an open sight alidade and plane table. Distances were determined on the roads by the speedometer on the automo­bile; the detailed survey in the immediate vicinity of the deposits was done with use of the Brunton compass and pac­ing. The purpose of Part II in this report is to determine if the bentonite deposits immediately west of Butte, Montana are of com­mercial importance and also to determine the use to which they are best suited.
