Map - Socorro County, New Mexico (Socorro County)

Socorro County (Condado de Socorro) is a county in the U.S. state of New Mexico. As of the 2010 census, the population was 17,866. The county seat is Socorro. The county was formed in 1852 as one of the original nine counties of New Mexico Territory. Socorro was originally the name given to a Native American village (see: Puebloan peoples) by Don Juan de Oñate in 1598. Having received vitally needed food and assistance from the native population, Oñate named the pueblo Socorro ("succor" in English).

Socorro County is home to multiple scientific research institutions including New Mexico Institute of Mining and Technology, the National Radio Astronomy Observatory and its associated Very Large Array, the Magdalena Ridge Observatory, and the Langmuir Laboratory for Atmospheric Research. Federal public lands in Socorro County include parts of the Cibola National Forest, the Bosque del Apache National Wildlife Refuge, the Sevilleta National Wildlife Refuge, the Bureau of Land Management (BLM) Socorro Field Office, parts of the Salinas Pueblo Missions National Monument, and parts of the El Camino Real de Tierra Adentro National Historic Trail.

Socorro County's history is intimately linked with the rich history of the surrounding area. Basham noted in his report documenting the archeological history of the Cibola National Forest's Magdalena Ranger District, which is almost entirely within Socorro County, that “[t]he heritage resources on the district are diverse and representative of nearly every prominent human evolutionary event known to anthropology. Evidence for human use of district lands date back 14,000 years to the Paleoindian period providing glimpses into the peopling of the New World and megafaunal extinction.“ Much of the now Magdalena Ranger District were a province of the Apache. Bands of Apache effectively controlled the Magdalena-Datil region from the seventeenth century until they were defeated in the Apache Wars in the late nineteenth century.

Outlaw renegades Butch Cassidy and the Wild Bunch and notorious Apaches like Cochise and Geronimo have ties to Socorro County's San Mateo Mountains. Vicks Peak was named after Victorio, “a Mimbreño Apache leader whose territory included much of the south and southwest New Mexico.” Famous for defying relocation orders in 1879 and leading his warriors “on a two-year reign of terror before he was killed,” Victorio is at least as highly regarded as Geronimo or Cochise among Apaches. Perhaps most famous outlaw was the Apache Kid whose supposed grave lies within the Apache Kid Wilderness. Stories of depredations by the Apache Kid, and of his demise, became so common and dramatic that in southwestern folklore they may be exceeded only by tales of lost Spanish gold. Native Americans lingered in the San Mateos well into the 1900s. We know this by an essay written by Aldo Leopold in 1919 where he documents stumbling upon the remains of a recently abandoned Indian hunting camp.

A mining rush followed the Apache wars – gold, silver, and copper were found in the mountains. It wasn't until this time that extensive use of the area by non-Native Americans occurred. While some mining activity, involving gold, silver, and copper, occurred in the southern part of the range near the end of the nineteenth century, the prospecting/mining remnants are barely visible today due to collapse, topographic screening, and vegetation regrowth. While miners combed the mountains for mineral riches during the late nineteenth and early twentieth centuries, stockmen drove tens of thousands of sheep and cattle to stockyards at the village of Magdalena, then linked by rail with Socorro. In fact, the last regularly used cattle trail in the United States stretched 125 miles westward from Magdalena. The route was formally known as the Magdalena Livestock Driveway, but more popularly known to cowboys and cattlemen as the Beefsteak Trail. The trail began use in 1865 and its peak was in 1919. The trail was used continually until trailing gave way to trucking and the trail officially closed in 1971.
