A bar chart, but the 'bars' are illustrations of mountains and they are crowded together on the page and overlap, with the smaller mounts in front of the larger ones. There is a scale along the left and right edges of the chart indicating the height of each peak. The mountain are in pastel colored groups, presumably according to geographic region. Each peak is numbered and there is a legend at the bottom of the chart with the names of the peaks according to the number. Volcanic peaks are illustrated with a fiery plume at the top and smoke drifting up.
