Valleys and Higher Elevation A series of V-shapes indicates a valley and the V’s point to higher elevation. biosystems.okstate.edu/Home/fharry/4112/600.../ContourLines.ppt

U Shapes and Ridge A series of U shapes indicates a ridge. The U shapes will point to lower elevation. biosystems.okstate.edu/Home/fharry/4112/600.../ContourLines.ppt

Hills and Depressions A series of closed contours with increasing elevation indicates a hill. Hills may be identified with a “+” with the elevations biosystems.okstate.edu/Home/fharry/4112/600.../ContourLines.ppt

Hills and Depressions--cont A series of closed contours with decreasing elevation indicates a depression. Depressions may be identified with a “-”. biosystems.okstate.edu/Home/fharry/4112/600.../ContourLines.ppt
