Introduction: By way of introduction a section will be described across the Devonian of the northeastern part of Monroe County, Pa., along the line of Brodhead Creek and the Delaware, Lackawanna and Western Railroad. The base of this section will rest on the Corniferous limestone well exposed in a railroad cut a mile south of East Stroudsburg and the termination will b6 in the Pocono, as exposed on the Pocono Mountains, from Mount Pocono to the ridge northwest of Tobyhanna.

The following report covers a reconnaissance for radioactive materials that was made in parts of Maine, New York, New Jersey, and Pennsylvania. It's primary objective was to examine the iron ore deposits and associated rocks in Adirondack Mountains of New York and the Highlands of New Jersey. Additionally, several deposits known or reported to contain radioactive minerals were examined to delimit their extent. However, most of the deposits examined are not significant as possible sources of radioactive elements and the data pertaining to them are summarized in tables provided.

Report discussing a 1948 geological examination of 7,662 miles of roadside rocks in Vermont, Connecticut, Rhode Island, and southeastern New York to find deposits of radioactive materials.

Report discussing reconnaissance for radioactive materials in parts of Maine, New York, New Jersey, and Pennsylvania during 1952. From Abstract: "The primary objective was to examine the iron ore deposits and associated rocks in the Adirondack Mountains of New York and the Highlands of New Jersey."

Report discussing an investigation of intrusive igneous rocks for radioactivity in New Jersey, New York, and New England during August and September 1951. This was aimed at finding uranium contents of economic significance in these rocks and determining the geological cause for any radioactivity. Results of the investigation are given by region, and a summary is included.

Report discussing uranium that was discovered in uraniferous rock in the Phillips mine-Camp Smith area of New York in 1953.

Report discussing a geological examination of 3,750 miles of roads in the Hudson Valley and Adirondack Mountains in eastern and Central New York state to find deposits of radioactive materials. The examination took place in August 1949.
