How many mountains in the U.S. have summit (peak) elevations between 20,350 feet and 9800 feet?

Specifically, in the United States, there are six hundred-twenty (620) mountains that have summit (peak) elevations between 6200 meters (20,350 feet) and 2759 meters (9800 feet).

In the United States, only Denali exceeds 6000 meters (19,685 feet) elevation. Then, there are four major summits that exceed 5000 meters (16,404 feet), nine exceed 4500 meters (14,764 feet), 104 exceed 4000 meters (13,123 feet), 220 exceed 3500 meters (11,483 feet), and 302 peaks/summits exceed 3000 meters (9843 feet) elevation.

Of the 620 U.S. mountains, 200 of the highest major peaks (summits) are located in the following states. Eighty-eight (88) are located in Colorado, 49 in Alaska, 22 in California, 14 in Wyoming, eight in New Mexico, five in Utah, four in Nevada, three in Montana, two in Washington, two in Hawaii, two in Idaho, and one in Arizona. Five of these peaks lie on the international border between Alaska and Yukon, and two lie on the international border between Alaska and British Columbia. The ten (10) highest summits/peaks of the United States are all located in Alaska.

Also, it is interesting to know that the topographic elevation of a summit measures the height of the summit above a geodetic sea level.
