E.L. Karlstein 1954 Journal (?) April 9 Doug Hubbard, Associate Naturalist at Yosemite, reports that Tioga Pass Road slated to be open by June 15, as is customary. A naturalist is usually at Glacier by end of June when public can get to Glacier Point. He directed me to Walter Hoyt, a Ranger now available at the Administration Building, who now operates weather station at museum and has kept Yosemite records for years. Hoyt let me see weather data sheets for past year. Some pertinent figures are here listed (readings taken daily at 5 P.M.): ^ Temperatures of.
