Reverse faults have the maximum and middle principal stressed
Thus we expect reverse faults to have 30 degree dips with the hanging
moving up. They are commonly called thrust faults.

70_100. Lewis thrust along the boundary in the valley between the dark
green of the forest and the brown of the rock above. This fault is
for about 50 km from the head of Marais pass on the left.
outcrop of the fault turns to the north at the right side of the photo.
