Rocky Mountain National Park, Colorado
(approx. 3000 ft. above the tree line)
Long's Peak, ca. 1924
July 19, 1924 Gerald Thorne "experienced the pleasure of visiting
this spot... From the crevices less than a pound of coarse granite soil
and roots of plants was collected, but from it over a thousand nematodes
( Nematodes From the Summit of Long's Peak, Colorado -G. Thorne, 1929)
On July 29, 2000 Tom Powers revisited this spot, collecting similar coarse granite soil from the crevices, in order to compare the Long's Peak nematode population of 1924 to that of 2000.
