Carson Sink

Carson Sink is a playa in the northeastern portion of the Carson Desert in present-day Nevada, United States of America, that was formerly the terminus of the Carson River. Today the sink is fed by drainage canals of the Truckee-Carson Irrigation District. The southeastern fringe of the sink, where the canals enter, is a wetland of the Central Basin and Range ecoregion.[1]

This is mostly included within the Fallon National Wildlife Refuge and the Stillwater Wildlife Management Area. This area serves as an important stopover for migrating waterfowl. The Sehoo Formation is in the south of the Carson Sink.[2]

Carson Sink and Lone Rock working areas

The Carson Sink and Lone Rock working areas are the northwest portion of both the Carson Sink and the US Naval Fallon Range Training Complex.[3] The Lone Rock working area includes the Bravo-20 range, which has numerous targets for combat aircraft training.[3]

Lone Rock is in the middle of a Bravo-20 live bombing area.[3] It is a solitary pinnacle of rock through the playa and it is held sacred by the Northern Paiute.[4]

History

The Carson Sink was a deep portion of the Pleistocene water body Lake Lahontan,[5] the lakebed of which is now the Lahontan Basin.

The Carson Trail, used during the California Gold Rush across the Lahontan Basin, included a section from through the Forty Mile Desert to the first drinkable water on the Carson River.[6] The Carson Sink station of the Pony Express was built in March 1860.[7]

In June 1952 two U.S. Air Force colonels flew a B-25 bomber from Hamilton Field near San Francisco to Colorado Springs, Colorado. While passing over Carson Sink, the two reportedly saw three unknown aircraft fly within 800 yards of their aircraft before speeding out of sight seconds later. Upon landing, the two colonels reported the incident to the Air Defence Command headquarters, who informed them that there were no military or civilian aircraft in the area at the time. The incident was never resolved and is known today as the Carson Sink UFO incident.[8]

In 1984, the natural dike between the Carson Sink and the Humboldt Sink was breached by the Nevada Department of Transportation to prevent Interstate 80 and the town of Lovelock from flooding due to unusually heavy snowfall in the preceding three years. The sinks remained connected by water for 3 years, until 1987.

gollark: Just because both sides don't like something doesn't make it good.
gollark: You just get politicians focusing on a small subset of states which have lots of EC votes and are not always going to be a majority for one party.
gollark: So it does not, in fact, provide equally powerful voices per state.
gollark: > Why should states remain in the nation if they aren't having an equally powerful voice? For example, why should Iowa stick around if they're just subservient to California's whims?Don't different states have different amounts of electors?
gollark: The electoral college appears to do something you could approximately describe as that but which is weirdly skewed in some ways.
