Selected data from thermal-spring areas, southwestern Montana

During 1975-77 the Montana district of the U.S. Geological Survey collected and assembled data describing the flow, temperature, and chemical characteristics of thermal and related waters. The work was part of an assessment of the geothermal resources of southwestern Montana, excluding Yellowstone Park. The purpose of this report is to present representative data from 24 thermal springs and 3 deep wells where water temperatures exceed 38°C (100°F).
