FRESNO CREEK (PRESIDIO COUNTY)
FRESNO CREEK (Presidio County). Fresno Creek, a major intermittent stream, rises on the west flank of the Solitario dome near Post Mountain in southeastern Presidio County (at 29°30' N, 103°49' W) and runs south for sixteen miles to its mouth on the Rio Grande, six miles west of Lajitas (at 29°17' N, 103°51' W). It rises in an area of Cretaceous limestones, crosses Tertiary deposits of sandstone, tuff, and igneous rocks, and ends in a Quaternary alluvium on the Rio Grande. The local terrain is surfaced by generally light reddish-brown to brown sands, clay loams, and rough stony areas. Sparse desert shrubs are the main vegetation in the vicinity.
