WALKER CREEK (Presidio County). Walker Creek rises in the Sierra Vieja Mountains in western Presidio County (at 30°27' N, 104°39' W) and flows in a southerly direction for twelve miles to its mouth on Capote Creek, four miles southwest of the southern edge of the Sierra Vieja Mountains (at 30°13' N, 104°38' W). Its course crosses Tertiary deposits of rhyolites and tuffs. The soils of the area are generally light reddish-brown to brown sands and clay loams, often rough and stony. The vegetation consists primarily of sparse desert shrubs. In August 1583 the entrada of Antonio de Espejo traveled down Walker Creek to the Rio Grande near Candelaria.
