Description

Sierra Blanca is set in the Chihuahuan Desert, six miles (9.7 km) northwest of the town of Sierra Blanca which is named after this mountain. [6] The volcanic peak ranks as the highest point in the Sierra Blanca range, [1] [4] the sixth-highest summit in the county and 54th-highest in the state. [3] It is a prominent landmark along Interstate 10 in Texas, as it is ranked 10th in topographic prominence in the state. [1] [3] Topographic relief is significant as the summit rises 2,400 feet (732 m) above the surrounding terrain in two miles (3.2 km). The mountain is a laccolith composed of late Oligocene rhyolite which intruded sedimentary layers of limestone, shale, and sandstone of Cretaceous age. [5] Based on the Köppen climate classification, the mountain is located in a hot arid climate zone with hot summers and mild winters. [7] Any scant precipitation runoff from the peak's slopes drains to the Rio Grande which is less than 20 miles to the southwest. The mountain's Spanish name translates as "White Mountain" which is attributable to white flowers which grow on the slopes, [8] [9] and may have been so named by the Spanish explorer, Francisco Vázquez de Coronado. [10] The mountain's toponym has been officially adopted by the United States Board on Geographic Names, [2] and has been reported in publications since at least 1890. [11] However, the town is named after the mountain, and the town was founded in 1881 at the completion point of a southern transcontinental railway southeast of the mountain where a silver spike was laid.

Blanca Peak is the fourth highest summit of the Rocky Mountains of North America and the U.S. state of Colorado. The ultra-prominent 14,351-foot (4,374 m) peak is the highest summit of the Sierra Blanca Massif, the Sangre de Cristo Range, and the Sangre de Cristo Mountains. The fourteener is located 9.6 miles (15.5 km) north by east of the Town of Blanca, on the drainage divide separating Rio Grande National Forest and Alamosa County from the Sangre de Cristo Land Grant and Costilla County. The summit is the highest point of both counties and the entire drainage basin of the Rio Grande. Below the steep North Face of Blanca Peak two live Glaciers once developed, until extinction sometime after 1903. North & South Blanca Glaciers were located at 37° 35N.,longitude 105° 28W. Blanca Peak is higher than any point in the United States east of its longitude.

<span class="mw-page-title-main">Cirque Peak (California)</span> Mountain summit in California

Cirque Peak is a 12,900-foot-elevation (3,900-meter) mountain summit located on the crest of the Sierra Nevada mountain range in California. It is situated on the common border of Tulare County with Inyo County, as well as the shared boundary of Golden Trout Wilderness and John Muir Wilderness, on land managed by Inyo National Forest. It is 14 miles (23 km) southwest of the community of Lone Pine, 7.7 miles (12.4 km) south-southeast of Mount Whitney, and 3.2 miles (5.1 km) south of Mount Langley, the nearest higher neighbor. Cirque Peak is the highest point of the Golden Trout Wilderness, and ranks as the 175th highest peak in California. Topographic relief is significant as it rises 1,800 feet above Cirque Lake in approximately one mile. The Pacific Crest Trail traverses the southwest slope of this mountain, providing an approach option. The mountain was apparently named in 1890 by Joseph Nisbet LeConte and companions who noted the remarkable cirque on the north aspect.
