Beginning in 1926, Fryxell spent the next nine summers in and around the Teton Range, which at the time was inaccessible by train or automobile. During three summers of field work for his dissertation, Fryxell spent almost all his time in
Jackson Hole, the valley in the eastern lee of the Tetons, studying the
moraines and glacial outwash from the mountains. He camped out, carrying his tent, rations, and down-filled sleeping bag with him as he traversed the valley floor. After his appointment as park naturalist in 1929, he was finally able to explore the mountains themselves. On his rare days off, he would rise as early as two o'clock in the morning to begin his ascent. Nearly always exploring alone, he climbed previously untraveled canyons, discovered hidden lakes, and summitted many of the range’s peaks for the first time. Fryxell returned to Grand Teton National Park every summer through 1934. During this time he founded the park’s museum and developed an interpretive curriculum for visitors – still finding time to blaze new trails up the mountains and log new discoveries on each trip. == Writing ==
