Grant Hiskes and John Hiskes, authors of the Discovery of YosemiteAbout the Authors

John Hiskes

John (on the right in photo) arrived in Berkley, CA in 1949 to attend the University. After receiving an M.A. degree in 1952 John worked for the U.C. Radiation Laboratory, receiving a Ph.D. in physics in 1960. Having discovered the fascinations of Yosemite during his college years, he launched a campaign to climb all the high points in the Park—a campaign that continues to this day but is frequently diverted into other explorations and excursions.

John discovered the possibilities of Nordic skiing, and once he recreated the legendary Snowshoe Thompson’s solo trek across the Sierra in the 1860’s. He and some friends then formed a ski touring group to make annual midwinter east-west traverses of the Sierra Nevada. John later joined with Ron Korner to found the Friends of Snow Creek Lodge, a group that worked successfully to offset the planned demolition of this historic old Lodge.

John retired from the Lawrence Livermore Laboratory in 1991 after a career in atomic and molecular physics and magnetic fusion. He currently pursues issues in cosmology, history, and astronomy, and he can often be found after dark at his observatory in Truckee, CA.

Grant then established his own company, SNOE (Sierra Nevada Outdoor Education).
