From abstract: A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be exposed in the area and of three manganiferous spring deposits was determined with portable Geiger-Mueller counters. At 86 localities 82 samples were taken of these formations and also of 10 ground and surface waters.

Abstract: The Free Enterprise property is located in the Boulder mining district, Jefferson County, Montana. Secondary uranium minerals occur here in small irregular concentrations in and adjacent to a narrow silicified fracture zone in quartz monzonite.

The investigator made a study of the history, philosophy, method, and operation of centralized purchasing as it now exists for the state-supported institutions in the State of Texas and other selected states (New Hampshire, Montana, Michigan, Nebraska, and Minnesota).

Photograph of the baptistry painting done by Perry for the Church of Christ in Missoula, Montana. Painting depicts a stream running over rocks with a tree lined bank, clouds, and mountains. Painting is photographed outside against a brick wall with a drainpipe.

Abstract: Secondary minerals of the uranite group occur in dense quartz veins and in altered aplitic granite along and near the crest of the east-trending ridge about one mile west of Clancy, Montana. Brief examination suggests that the radioactive minerals are erratically distributed, but a more thorough study of the area will be made by the Geological Survey during the coming field season.
