Description

Published references call the structure "Lee Fault," but it is a fault zone consisting of several northeast-trending, closely spaced, parallel or branching fractures that are downthrown as much as 450 feet (140 m) on the southeast side. It dies out to the northeast on the south flank of the Eagle Valley Syncline and merges with other named faults to the southwest.
