LOS MORTEROS CREEK. Los Morteros Creek (Los Morteros Arroyo) rises a mile east of the Zapata county line and less than a mile south of U.S. Highway 83 in southwestern Starr County (at 26°37' N, 99°06' W) and runs south seven miles to its mouth on the Rio Grande, west of Salineño (at 26°31' N, 99°08' W). The name is Spanish for mortar or a piece of ordnance; the appearance of the local soil suggests the name mortar. The stream traverses flat to rolling terrain with steep margins, surfaced by shallow to deep sandy loams that support grasses and, along the creek, pecans and willows.
