Height so prominent it was Garza County's earliest bench mark, designated by peg-legged surveyor Jasper Hays, who in 1877-1878 was marking bounds of Llano Ranch, first property to be occupied by settlers in county. Hays began at a corner established for the Houston and Great Northern Railroad Company near the White River in Crosby County, and shot west toward this peak. Tradition has it that a member of Hays' crew died and was buried near this peak, which was afterward named for him. Local heights named for natural wonders include "The Ice Cream Cones," "Cow Head Mesa," "Indian Head Point," and "The Chimneys," Other interesting uplands are "Two Bush Hill," "The Devil's Breakfast Table," "Needlepoint Peak," and "Buffalo Point." Two balanced rocks known to early settlers have now disappeared because of wind and weather erosion. Duffy's Peak, like most of the scenic formations, is sandstone, clay and sand. It still figures in local land transactions, as Hays' original notes (unearthed from Mason jars he buried on the peak) formed basis for later surveys-- including those of A. L. Marhoff in 1906, establishing boundaries for the farm colony of "Cereal King" C. W. Post. 1969
