Study of Clay Shale Slopes Along the Panama Canal, Report 3: Engineering Analyses of Slides and Strength Properties of Clay Shales Along the Gaillard Cut
"The results of the engineering studies and analyses which provide guidance on shear strength parameters applicable to the stability evaluation of existing slopes along the Gaillard Cut, the effects of future modifications, and evaluation of newly excavated slopes in clay shales are summarized in this report" (abstract). This report includes the appendices containing enginering data, characteristics of materials, analysis of past slides, active slopes, and hydrographic survey data.
Some Engineering Problems of the Panama Canal in Their Relation to Geology and Topography
Report issued by the Bureau of Mines over issues encountered during construction of the Panama Canal. As stated in the introduction, "this report aims to discuss, from the viewpoint of the mining geologist, the bearing of topographic and geologic conditions on certain problems that arose in the construction of the Panama Canal" (p. 7).

Mineral Deposits of Central America
From introduction: This report is based on investigations carried on by the Geological Survey (U. S. Department of the Interior) under the auspices of the Interdepartmental Committee on Scientific and Cultural Cooperation (U. S. Department of State) and the Foreign Economic Administration. The function of the last two agencies is presently carried on by the International Cooperation Administration. Roberts is responsible for the text of this report and for the compilation of the geologic map. He was in Central America from January to April 1942 under a program of scientific and technical cooperation with the American Republics sponsored by the Department of State, and mapped manganese deposits in Costa Rica and manganese and antimony deposits in Honduras.
