The Spanish name for the Pinacate Peaks geographic feature is the Sierra Pinacate, which is used in their homeland of Mexico.

Location

The Pinacate Peaks lie just north of the fishing resort of Puerto Peñasco. The tallest of the peaks is Cerro del Pinacate (also called Volcan Santa Clara), elevation 3,904 feet (1,190 m). The Mexican Spanish word pinacate is derived from the Nahuatl word for the endemic desert stink beetle, pinacatl.

Natural History

Geology

The volcanoes here have erupted here sporadically since about 4 million years ago, probably in association with the opening of the Gulf of California. The most recent volcanic activity was about 11,000 years ago. The Pinacate Desert is home to the largest sand dunes of the Americas.[2]

Flora and fauna

A variety of flora and fauna occur in the Pinacate Mountains, including the sculptural Elephant Tree, Bursera microphylla.[3]

Human history

Padre Eusebio Kino, founder of many Spanish missions in the Sonoran Desert, explored here in 1698 and several times later.

NASA sent astronauts here starting in 1965 for geologic training, given the similarity of the terrain to the lunar surface, and included training models of lunar surface equipment. Apollo 14's Alan Shepard and Ed Mitchell, and Apollo 17's Jack Schmitt trained here in Feb. 1970.[4]
