Cougar mine
Strike-slip fault, right-lateral offset—Identity and existence certain, location accurate. Long dash shows location approximate. Short dash shows location inferred. Arrows show relative motion
Front of ore roll in sandstone—Identity and existence certain, location accurate. Long dash shows location approximate. Dots shows location inferred. Arrow is on concave side of roll; queried where inferred
Double ore roll front in sandstone—Identity and existence certain, location accurate. Arrow is on concave side of roll
Inclined fault—Showing dip value and direction
Current lineation in sandstone layers that contain ore bodies
Ripple marks—Symbol is normal to troughs of ripples

Portal
Uranium-vanadium roll ore bodies, fossil logs, current lineations, and faults. Diagonal lines indicate positions of cross sections depicted in plate 15. Geology mapped by D.R. Shawe, E.L. Boudette, W.B. Rogers, N.L. Archbold, and G.C. Simmons, by Brunton-and-tape method, 1953–1957. Control by transit survey.
