Sandia Mountains
From Free net encyclopedia
The Sandia Mountains are a mountain range located in Bernalillo and Sandoval counties, immediately to the Northeast of Albuquerque, New Mexico. The range is largely within Cibola National Forest. The highest point is Sandia Crest at 10,678 ft (3,255 m). South Sandia Peak is 9,702 ft (2,957 m) in elevation.
Sandia means watermelon in Spanish, and is popularly believed to be a reference to the red color of the mountains at sunset. Also, when viewed from the west, the profile of the mountains is a long ridge, with a thin zone of green conifers near the top, suggesting the "rind" of the watermelon. However, Robert Julyan notes in The Place Names of New Mexico, "the most likely explanation is the one believed by the Sandia Indians: the Spaniards, when they encountered the Pueblo in 1540, called it Sandia, because they thought the squash growing there were watermelons, and the name Sandia soon was transferred to the mountains east of the pueblo." He also notes that the Sandia Pueblo Indians call the mountain Bien Mur, "big mountain."

Layout of the range
The Sandias are a small range, consisting of a single north-south ridge, which rises to two major summits, Sandia Crest and South Sandia Peak. The range measures approximately 17 miles (26km) north-south, and the width in the east-west direction varies from 4 to 8 miles (6 to 12km). The west side of the range is steep and rugged, with a number of sheer rock walls and towers near Sandia Crest. The east side has a gentler slope.
Geology
The Sandia Mountains are a fault-block range, on the eastern edge of the Rio Grande Rift Valley. The core of the range consists of Sandia Granite, approximately 1.4 billion years old. (There is also some metamorphic rock of age 1.7 billion years.) This is topped by a relatively thin layer (approximately 300 feet/100 metres) of sedimentary rock (mostly limestone, and some sandstone) of Pennsylvanian age (circa 300 million years ago). The Sandias were uplifted in the last 10 million years as part of the formation of the Rio Grande Rift.
Ecology
The Sandias encompass four different named life zones due to the large elevation change, and the resulting changes in temperature and amount of precipitation, from base to top. The grassland at the western base of the mountain (the edge of the city of Albuquerque) is part of the Upper Sonoran Zone. From 5,500 feet elevation to 7,200 feet (all of these elevations are approximate), the Upper Sonoran Zone continues, but notable differences occur: one first finds a zone of primarily juniper, then a mixed Piñon-Juniper zone. From 7,200 to 7,800 feet, in the Transition Zone, Ponderosa Pine dominates. From 7,800 to 9,800 feet, a mixture of conifers occurs in the Canadian Zone. Finally, from 9,800 feet to Sandia Crest at 10,678 feet, spruce and fir dominate the Hudsonian Zone.
Access and recreation
There are two easy ways to reach the top of the Sandias. The Sandia Peak Tramway ascends from the west side to a point on the crestline about 1.5 miles south of Sandia Crest, at the top of the Sandia Peak Ski Area, located on the east side. A road (NM 536) from the east provides access to the bottom of the ski area and also to Sandia Crest itself, where there is a gift shop, restaurant, and a large electronic communications site. Along the road there are numerous picnic and recreation sites.
There are no developed campgrounds in the Sandias. Numerous hiking trails exist on both sides of the range. Much of the west side of the range is included in the Sandia Mountain Wilderness; the trails on that side are steeper, and water is very scarce.
The rock walls and pinnacles on the west side of the range provide abundant rock climbing opportunities, from bouldering and top-roping to multiday big wall climbs on the Shield, the largest rock feature on the mountain. However the long hikes (often off-trail) required to reach many of the climbs, and the variable quality of rock (often poor), prevent the Sandias from being a major climbing destination.
History
The Sandias contain a location notable for prehistoric archaeology: the Sandia Cave is believed to have been inhabited 10000 to 12000 years ago by the Sandia Man. The cave can be accessed via a 1/2 mile trail in Las Huertas Canyon, on the northeast side of the range, near Placitas, New Mexico.
Ancestral and early Pueblo peoples have lived in the Sandia Mountains area for thousands of years. Examples of previous Pueblo settlements, now unoccupied, include Tijeras Pueblo and Pa'ako Pueblo, both founded around 700 years ago. Sandia Pueblo is a modern pueblo, abutting the Sandia Mountains on the northwest side of the range. Some of the foothills of the range are on Sandia Pueblo land; there have been disputes in the past between the Pueblo, the Forest Service, and private landowners over rights to various parts of the range. The people of Sandia Pueblo consider the mountains a sacred place.
