Using Map T-22b, the “SP Mountain, Arizona,” quadrangle (scale 1:24,000; contour interval 40 feet), calculate the gradient of SP Mountain (35°34'56"N, 111°37'55"W) from the north base of the cone (at the 6200' contour) toward the crater rim. On the edge of a piece of paper measure out a distance of 0.2 miles using the graphic map scale, and then determine the elevation change over that distance.
In this problem, you will compute the gradients of Mauna Loa in Hawai‘i, Mount Vsevidof in Alaska, and SP Mountain in Arizona. (You may also determine the elevation changes and distances needed to calculate these gradients by using Google Earth™.) The recommended starting point and distance to measure are given for all three volcanoes.
