a yearlong season. The allotment was restocked after 2002 due to drought, and has been below maximum rates since then. The allotment contains 18 earth tanks, 7 wells, 31 miles of pipelines, 14 drinking troughs, 10 storage tanks, and 77 miles of fencing. In 2006, the water supply was substantially improved by the completion of the Caja del Rio Pipeline. Points of interest From 2004, the Caja has been the focus of a grass roots campaign to develop recreational trail uses. The purpose of this campaign is to augment use of the Caja, rather than replacing grazing. The trail system is used primarily by mountain bike and horse riders. Wild horses The United States Forest Service has designated Caja del Rio a Wild Horse Territory, and manages a herd of mustangs there. A separate band of feral horses in the vicinity is not managed; its members are thought to be domestic horses recently turned loose to fend for themselves. Diablo Canyon Caja del Rio Canyon (known locally as Diablo Canyon), is a popular local rock climbing area on the northern section of Canada Ancha, near its confluence with the Rio Grande. This area can be accessed by Camino La Tierra and Old Buckman Road. Although the area is not marked, it has an undeveloped but very large parking area at its east end. The canyon walls include impressive trap rocks. The flat, sand bottom of the canyon is subject to spectacular flash floods during the summer monsoon season. The hike from Diablo Canyon to the Rio Grande is both scenic and easy White Rock Canyon. The wash is also popular with horse riders. After passing Diablo Canyon, Old Buckman Road continues to the site of Buckman, a former logging town and depot of the narrow gauge Chili Line. The Rio Grande can be forded in some seasons at Buckman. In fact, this crossing was a major transportation route between Santa Fe and the Pajarito Plateau. Diablo Canyon was a filming location for the 2007 film 3:10 to Yuma. Caja trails The Caja has around 100 miles of mapped trails. Some of the more notable trails include: Chino Mesa Trail – 8 miles (one way) of two-track road running north from 1100 Well to overlook of White Rock Canyon near Pinabete Tanks Montoso Peak Trail – 12 miles (loop) of two-track road running west from 1100 Well around north end of
