History

In 1947 the United States Atomic Energy Commission acquired land from the United States Forest Service to build a temporary community to house construction workers. That community was the first White Rock, which was abandoned by 1953. By 1958 all of the old White Rock buildings had been demolished or removed. The second and present White Rock was begun in 1962.

The center of the town of Los Alamos is 9 miles (14 km) northwest of White Rock, via New Mexico State Roads 4 and 502. A gated entrance to Los Alamos National Laboratory is on Pajarito Road, accessed directly from White Rock.

According to the United States Census Bureau, the White Rock CDP has a total area of 7.1 square miles (18.4 km), of which 0.04 square miles (0.1 km), or 0.59%, are water.

White Rock Canyon

Largely undeveloped White Rock Canyon, on the eastern edge of the community, provides a wilderness recreation area heavily used by residents of White Rock and Santa Fe. The canyon was carved through basalt and tuff by the south-flowing Rio Grande. The canyon runs from the Otowi Suspension Bridge in the north and to Cochiti Dam in the south, with many smaller tributary canyons such Los Alamos, Mortandad, Water, Ancho, Frijoles, and Capulin Canyon. White Rock is situated on a portion of the west side of the canyon along with Bandelier National Monument, a section of Los Alamos National Laboratory, San Ildefonso Pueblo, Cochiti Pueblo, and Santa Fe National Forest. Across the river to the east rises the Caja del Rio.

For a few decades the Chili Line, a narrow gauge railroad, ran on the east bank of the river as far south as the mouth of Diablo Canyon; some day the Rio Grande Trail may occupy the abandoned right of way.

Averaging 1,000 feet (300 m) deep, the canyon provides spectacular vistas, rugged terrain and home to rare plant species as well as endangered animal species. Along the rim of the canyon are many basalt cliffs that are used by rock climbers.

The trailhead begins about 100 yards southwest of the overlook viewing platform, and is accessible from a small parking lot at the end of the last side road branching east off Overlook Road. Partway to the river a meadow lies on top of a large Toreva block bench (a large piece of terrain which has moved downhill as a unit). At the midway point, the material underfoot changes from dark sharp basaltic rocks to light rounded granitic stones. The trail passes a large spring seeping from scree as the trail nears the Rio Grande. This water and water from the river are not safe to drink.

This trail, also known as Pajarito Springs Trail, is accessible from Piedra Loop in La Senda. Numerous petroglyphs appear along the way, unseen by many hikers concentrating on their footing on this very steep and challenging trail. The rock drawings are varied in style, from Kokopelli to abstract and geometric designs. The local Tewa may have imported some designs from Native Americans of the Great Plains. The Pajarito Springs are several in number and combine to form a small creek flowing into a pool via a small waterfall. The trail continues to the Rio Grande.
