This trail is still visible a few miles west of the Jornada Experimental Range. 1858 First land survey of the area which later formed the Jornada Experimental Range, with records made of soils and vegetation. 1880 Beginning of a decade during which ranches were established at springs in the San Andres Mountains and watering points on the Jornada basin. 1901 C.T. Turney, a rancher, settled at site of present-day Jornada Headquarters and gained control of water sources in the area. 1904 E.O. Wooton, visionary botanist with the New Mexico College of Agriculture and Mechanic Arts, started cooperative range investigations with C.T. Turney and other ranchers in southern New Mexico. 1912 Largely through the efforts of Wooton, the Public Domain lands comprising the C.T.
