Determine the approximate amount of visible vertical displacement along each of the three fault scarps at their intersection with line AB (to determine the amount of visible displacement, measure the height [relief] of each fault scarp; it may be easiest to count the number of contour lines shown on each scarp to determine the elevation change).
The following questions are based on the “Mt. Dome, California,” quadrangle (Map T-24; enlarged to scale 1:48,000; contour interval 40 feet) and the stereogram of the same region (Figure 36-5; north is to the left side of the page). Three prominent fault scarps can be seen running north to south across the map, and will be referred to as the “western” fault, the “central” fault, and the “eastern” fault. These fault scarps are the result of normal faulting (41°49'39"N, 121°33'15"W). Western Fault: _______ feet Central Fault: _______ feet Eastern Fault: ________ feet
