The Potash reach is one of the least sinuous (average sinuosity 1.1) of the 20 reaches defined by this project. This generally south-trending reach extends for 10 km from Bkm 100 just upstream of Potash to Bkm 90 near the south end of Pyramid Butte. This reach flows within a transverse valley that is cut within sub-horizontal strata of the lower Cutler Formation and, for about one 1.6 km, within the Honaker Trail Fm. This valley of the Potash reach is highly variable in shape, ranging from 825 to more than 1525 m wide and 60 to 275 m deep. The average gradient along this reach is approximately 0.03% slope. This reach has a long history of industrial activity both in the river bottom and in the adjacent uplands....
