Strike Wind River Mountains, WY. Check and double-click the Problem 2 placemark. To approximate strike, use the Line feature in the Ruler tool (make sure that the Ruler tool and the Status Bar are using meters) to determine the elevation at the point of the Problem 2 placemark icon by hovering the cursor over it and looking at the Status Bar (~1,835 m). Now draw a line from the Problem 2 placemark using the Ruler tool to the right (NW) such that you click the second point of the line at a location at the exact same elevation (~1,835 m). Use the heading of this horizontal line in the Ruler tool dialog box to determine the orientation of strike (000360) for these rock layers. Note: Directions can be visualized as a 360 circle with N = 000 and 360, E = 090, S = 180, and W = 270. This approximation works because were assuming that the flat part of the flatiron approximates a bedding plane surface.
