Twin Chimneys

Surveyors needed landmarks because Garza County is rough, broken country. Its 914 square miles lie partly on the Llano Estacado and partly in the breaks of the lower plains, drained by tributaries of the Brazos River, with elevations running from 2,100 to 3,000 feet. Sandy, loamy and clay soils carry grass, small mesquite, thorny scrub and cacti. Rainfall averages just under nineteen inches a year; January lows average 28 degrees and July highs 95, and the growing season runs about 216 days.

What the plaque says

Twin Chimneys (100 Yards North) Used as a landmark in the 19th century by surveyors sighting from Duffy's Peak, located ten miles northeast. Jasper Hays, earliest recorded surveyor of this area, used the peaks during 1877-78 for charting the Llano Ranch, later bought by C. W. Post, the cereal king. Hays established, in addition, lines from which section surveys were made. Civil engineer A. L. Marhoff, using the original field notes and book of Hays, surveyed the land bought by Post, 1906. This included the section on which the town of Post was founded, 1907, as well as other property. 1970
