The [[Postmaster General]] thought the name too common and suggested that the place be named Arco for [[Georg von Arco]] (1869-1940) of [[Germany]] who was visiting Washington, D.C. at the time. Georg von Arco was an inventor and a pioneer in the field of radio transmission and would become the lead engineer of [[Telefunken]], a German company founded in 1903 that produced [[radio]] [[vacuum tube]]s.

== History ==
Arco was named as early as 1860 based on the name of a local rancher, Louis Arco.<ref>{{cite book |last=Anderson |first=Abraham C. |author-link= |date=1940 |title=Trails of Early Idaho: The Pioneer Life of George W. Goodhart |url=https://www.abebooks.com/Trails-Early-Idaho-Pioneer-Life-George/17098100769/bd |location=Caldwell, Idaho |publisher=Caxton Printers |page=257 |isbn=}}</ref> Louis Arco is also mentioned in the National Park Service’s Teacher's Guide to Craters of the Moon with the line “[around] 1862 Louis Arco establishe[d] a ranch and trading post at Arco."


Arco was the first community in the world ever to be lit by electricity generated by [[nuclear power]]. This occurred on July 17, 1955, powered by a [[Nuclear reactor technology|reactor]] (see ''[[BORAX experiments]]'') at the nearby "National Reactor Testing Station" (NRTS), which is now the [[Idaho National Laboratory]]. NRTS made further history on January 3, 1961, when the [[SL-1]] reactor melted down, causing three deaths. It was the world's first (and the U.S.' only) fatal reactor accident.
Arco was the first community in the world ever to be lit by electricity generated solely by [[nuclear power]]. This occurred for about an hour on July 17, 1955, powered by [[Argonne National Laboratory]]’s [[BORAX experiments|BORAX-III]] reactor at the nearby National Reactor Testing Station (NRTS),<!-- which eventually became the site of the Idaho National Energy Laboratory,--> now the [[Idaho National Laboratory]].<ref>{{cite web |url=http://www.ne.anl.gov/About/reactors/borax3/index.shtml |title=AEC Press release for BORAX-III lighting Arco, Idaho |publisher=United States Department of Energy, Argonne National Laboratory |year=1999 |access-date=2012-07-26}}</ref> NRTS made further history on January 3, 1961, when the [[SL-1#Accident and response|SL-1 reactor]] was destroyed through an operator maintenance error, with the ensuing steam explosion causing the deaths of all three personnel present.

Arco is a city in Butte County, Idaho, United States. The population was 879 as of the 2020 United States census, down from 995 at the 2010 census.[4][5] Arco is the county seat and largest city in Butte County.[6]

History

[edit]

Arco was named as early as 1860 based on the name of a local rancher, Louis Arco.[7] Louis Arco is also mentioned in the National Park Service’s Teacher's Guide to Craters of the Moon with the line “[around] 1862 Louis Arco establishe[d] a ranch and trading post at Arco."

Arco was the first community in the world ever to be lit by electricity generated solely by nuclear power. This occurred for about an hour on July 17, 1955, powered by Argonne National Laboratory’s BORAX-III reactor at the nearby National Reactor Testing Station (NRTS), now the Idaho National Laboratory.[8] NRTS made further history on January 3, 1961, when the SL-1 reactor was destroyed through an operator maintenance error, with the ensuing steam explosion causing the deaths of all three personnel present. It was the world's first and the United States' only fatal reactor accident.[9]

Economy

[edit]

The town's economic base is primarily derived from the Idaho National Laboratory (formerly the Idaho National Engineering Laboratory or INEL), agricultural products, and recreation in the Lost River Valley.

Highways

Geography

[edit]

Arco is located along the Big Lost River[10] and is a gateway to the Lost River Range from the Snake River Plain. Craters of the Moon National Monument is located along U.S. Route 20, southwest of the city. The Idaho National Laboratory (INL) is located east of Arco.

Arco Peak, located two mile north of the community at an elevation of 7547 feet, rises 2220 feet above the city.[10]

According to the United States Census Bureau, the city has a total area of 1.07 square miles (2.77 km2), of which, 1.06 square miles (2.75 km2) is land and 0.01 square miles (0.03 km2) is water.[11]

In town, the most striking physical feature is Number Hill, a rocky hill with numbers painted all over it. Butte County High School has a tradition of each class since 1920 painting its graduation year on the face of hill.[12]
