This report discusses aeromagnetic data that was obtained from uranium anomalies discovered in the Milbank quadrangle of South Dakota, North Dakota, and Minnesota.

This report discusses aeromagnetic data that was obtained from uranium anomalies discovered in the New Ulm quadrangle of Minnesota.

This report discusses aeromagnetic data that was obtained from uranium anomalies discovered in the River Falls quadrangle of Minnesota and North Dakota.

From purpose and scope: The purpose of this investigation is to 1) study the hydrologic system in a glaciated terrain typified by numerous lakes, with particular focus on the effects of lake-ground-water interchange, 2) simulate the natural system by using two digital modeling methods--areal (map view) and vertical section, and 3) evaluate the utility of the models and determine the kinds and amount of basic data needed to obtain reasonable simulations.

The following report discusses the findings from the Red River Valley drilling project that began in early June, 1977 and completed in October.

Report issued by the Bureau of Mines over studies conducted on the copper-nickel deposits of Lake County, Minnesota. As stated in the introduction, "this report describes the procedures and results of the drilling program as well as the metallurgical work and laboratory studies" (p. 1). This report includes tables, maps, and illustrations.

The report consists of three principal sections; environmental setting, water resource management, and the hydrologic system. The environmental setting describes the land and people as related to water resources. The section on water resource management is intended to provide practical information needed for the planning and management of water resources. The section on the hydrologic system is a more technical discussion of water in the Red River basin. The section on water management can be used to locate the water, determine the amount available and its quality; whereas, the section on the hydrologic system describes the operation of the system how water moves through the system and why the quality is as it is.
