Locate the outcrop of this marker bed given the three exposures indicated. Construct structure contours on the bed. Locate the intersections of like contours and locate the intersection of the bed with the hillsides 4. Sketch the valley and ridge crossings. Interpolate to find the most likely location.
Exceptions occur when the slope of the topography is steeper than the structure.
Locate the outcrop of this marker bed. Construct structure contours on the bed. Locate the intersections of like contours and locate the intersection of the bed with the hillsides. Note that there is no way for the outcrop band to exit the 700-800 meter elevation interval shown in purple. Thus, the only possible conclusion is that the outcrop band closes around the end of the ridge, making a V that points down the ridge.
