Abstract
A map showing freshwater heads for the Ordovician Red River Formation, Bighorn Dolomite, and equivalent rocks has been prepared as part of a study to determine the water-resources potential of the Mississippian Madison Limestone and associated rocks in the Northern Great Plains of Montana, North and South Dakota, and Wyoming. Most of the data used to prepare the map are from drill-stem tests of exploration and development wells drilled by the petroleum industry from 1964 to 1978. A short explanation describes the seven categories of reliability used to evaluate the drill-stem-test data and identifies several factors that might explain the apparent anomalous highs and lows on the potentiometric surface. The map is at a scale of 1:1,000 ,000 and the potentiometric contour interval is 100 feet. (USGS)
