McDermitt, Nevada and Oregon
# McDermitt, Nevada and Oregon

McDermitt is an unincorporated community straddling the Nevada–Oregon border, in Humboldt County, Nevada, and Malheur County, Oregon, United States. McDermitt's economy has historically been based on mining, ranching, and farming. The last mining operation closed in 1990, resulting in a steady decline in population.

As of the 2010 census, the combined population was 513. Seventy-five percent of the residents were American Indian, predominantly Northern Paiute of the Fort McDermitt Indian Reservation, whose members include Shoshone people.

## History

The community, originally called Dugout, was named after Fort McDermit. It was named after Lt. Col. Charles McDermit, commander of the Military District of Nevada, who was killed by Native Americans in a skirmish in the area in 1865. It is not known why there is a discrepancy in the spelling. Fort McDermit, which was five miles (8.0 km) outside the current township, was originally established to protect the stagecoach route from Virginia City through Winnemucca to Silver City, Idaho Territory. The stage road was the military's most important transportation route in southeast Oregon. The township of Dugout was established as support for Fort McDermit.

## Geography and climate

The community is on U.S. Highway 95, 73 miles (117 km) north of Winnemucca. The elevation of McDermitt is 4,432 feet (1,351 m) above sea level.

McDermitt is in the Oregon High Desert with a desert climate (Köppen climate classification BSk), averaging 9.2 inches (230 mm) of rain annually with hot, dry summers and cold winters. Most precipitation (47%) occurs from March through June. About 23% occurs from September through November, and 25% from December through February, much as snow.

The McDermitt area boasts the longest climatic record in Nevada, with data beginning in 1866. The earliest Nevada climate stations were at Army posts. The U.S. Army Signal Corps was responsible for weather duty in the late 19th century and established the National Weather Service in 1870.

## Demographics

For statistical purposes, the census bureau has allocated McDermitt two census-designated places (CDPs), McDermitt, Nevada and Fort McDermitt, Nevada. The Oregon portion of McDermitt is not part of the McDermitt CDP, but is included in the Ontario, OR–ID Micropolitan Statistical Area. Essentially the Fort McDermitt CDP entails the Fort McDermitt Indian Reservation and the McDermitt CDP entails the adjoining McDermitt township.

## Economy

McDermitt's economy has historically been based on mining, ranching and farming. In the period 1917 to 1989 it was home to four nationally significant mercury mines in the McDermitt Caldera – Bretz, Opalite, Cordero and McDermitt – which from 1933 to 1989 were the largest producers in North America. In 1985 of the 16,530 flasks of mercury (each containing 76 pounds (34 kg) produced in the US, 16,337 came from the McDermitt Mine. The closure of mercury mining in 1990 resulted in a significant decline in population.

Significant gold mines in the nearby Santa Rosa Mountains were the National that produced in excess of 200,000 troy ounces (6,200 kg), and the Buckskin National that produced 24,000 troy ounces (750 kg) of gold and 300,000 troy ounces (9,300 kg) of silver over the period 1906–1941.

Current development activities that may result in renewed mining are at Cordero (gold and silver), Cordero (gallium), Buckskin-National (gold-silver), Aurora (uranium) and Disaster Peak (gold). The largest employers in McDermitt are the Say When Bar, Restaurant & Casino and the McDermitt Combined School.

## Points of interest

The state line goes through the White Horse Inn, a historical landmark now being restored, which was a saloon, hotel, and (reportedly) brothel. When it was open, food could be ordered and paid for in Oregon, avoiding the Nevada state sales tax.

## Education

Humboldt County School District operates the McDermitt Combined School, a kindergarten–twelfth grade (K–12) school, in the Nevada side.

The Oregon side is zoned to McDermitt School District 51, a school district, governed by a board of directors, which sends all of its students to McDermitt Combined in Nevada and which does not have any employees. Circa 2006, 16 students, of all grade levels, lived in the district. In 2006 the district possessed a school building that was no longer used.

The section of Malheur County in which McDermitt, Oregon is located in is not in any community college district.

McDermitt has a public library, a branch of the Humboldt County Library.
