The Sandias are a small range, a part of the Basin and Range Province, but built by a different phenomenon known as rifting, consisting of a single north–south ridge, which rises to two major summits: Sandia Crest and South Sandia Peak, 9,782 ft (2,982 m). The range measures approximately 17 miles (27 km) north-south, and the width in the ...
The Sandia Formation is mostly shale with some sandstone and conglomerate but only minor limestone beds, with the coarser sediments towards its base. Variations in thickness indicate deposition on an eroded Precambrian surface. [1] The formation reaches its maximum thickness of 1,530 meters (5,020 feet) in the northern Sangre de Cristo ...
In 1903, C.R. Keyes applied the name, Madera limestone, to what he identified as upper Carboniferous beds in the Sandia Mountains. The unit was named for the town of La Madera. [1] The name was subsequently applied to Pennsylvanian marine limestones throughout central and northern New Mexico.
The Sandia Mountain Wilderness has one of the longest tramways in the world, traveling 2.7 miles (4.3 km) and climbing nearly 4,000 feet (1,200 m) to the crest of the Sandias. The Sandia Peak Aerial Tramway was designed by a team of Swiss engineers that had designed similar systems in the Alps. The tram has never had an accident or injury since ...
Sandia Granite with xenolith. The Sandia granite is prominently exposed along the east flank of the Rio Grande rift, with almost 1.5 kilometres (4,900 feet) of exposure at Sandia Crest. It extends from Placitas to Tijeras Canyon. Its radiometric age is 1453±12 Ma. The pluton is a single body with significant heterogeneities.
Sandia Crest. Sandia Crest, also known locally as Sandia Peak or simply as the Crest, [2] is a mountain ridge that, at 10,679 feet (3,255 m), is the highpoint of the Sandia–Manzano Mountains, and is located in the Sandia Mountains of Bernalillo County, New Mexico, United States. Instead of a true summit or topographic peak, this range climbs ...
The Gray Mesa Formation is a geologic formation in New Mexico. Its fossil assemblage dates the formation to the Moscovian age of the Pennsylvanian . The formation as presently defined includes outcrops previously assigned to many local units, including the Los Moyos Formation, the Armendaris Group, and the Nakaye Formation .
Albuquerque Basin. The Albuquerque Basin (or Middle Rio Grande Basin[1]) is a structural basin and ecoregion within the Rio Grande rift in central New Mexico. It contains the city of Albuquerque. Geologically, the Albuquerque Basin is a half-graben that slopes down towards the east to terminate on the Sandia and Manzano mountains. [2]
