SPENCER CREEK. Spencer Creek rises at Spencer Springs in the
southeastern Chinati Mountains in southwest Presidio County (at
29°48' N, 104°27' W) and runs southwest for fourteen miles to
its mouth on the Rio Grande, one mile below Adobes (at 29°42' N,
104°31' W). It crosses desert mountain terrain of sedimentary
deposits and inactive alluvial fans of gravel and sand that
support sparse grasses, cacti, and desert shrubs. The creek was
named for John Spencer, an early Presidio County settler, who
operated a horse ranch on the creek near Indio in the 1850s. The
