| Note générale : |
The shallow groundwater system in the northern powder river basin consists of upper cretaceous to holocene aquifers overlying the bearpaw shale-namely, the fox hills sandstone/ hell, creek, fort union, and wasatch formations/ terrace deposits, and alluvium. Ground-water flow above the bearfow shale can be divided into two general flow patterns. An upper flow pattern occurs in aquifers at depths of less than about 200 feet and occurs primarily as localized flow controlled by the surface topography. A lower flow pattern occurs in aquifer of depths from about 200 to 1,200 feet and exhibits a more regional flow, which is generally northward toward the yellowstone river with significant flow toward the powder and tongue rivers. |
