This photograph was taken early in the morning in the canyon of the Middle Fork of the San Joaquin River, on a solo trail run from Agnew Meadows to Tuolumne Meadows in Yosemite National Park, in the Summer of 1986 or 1987. My route followed the river trail to Thousand Island Lake, and then the PCT over Island and Donohue Passes, and down Lyell Canyon to the Tioga Road. It was a wonderful and adventurous run in a stunning area.
