'''Siskiyou County''' ({{IPAc-en|ˈ|s|ɪ|s|k|juː|audio=En-us-siskiyou.ogg}} {{respell|SISK|yoo}}) is a [[county (United States)|county]] located in the northwestern portion of the [[U.S. state]] of [[California]]. As of the [[2020 United States census|2020 census]], the population was 44,076.<ref name="QF">{{cite web|title=State & County QuickFacts|url=https://www.census.gov/quickfacts/fact/table/siskiyoucountycalifornia|publisher=United States Census Bureau|access-date=December 6, 2021}}</ref> Its [[county seat]] is [[Yreka, California|Yreka]] and its highest point is [[Mount Shasta]].<ref name="GR6">{{cite web|url=http://www.naco.org/Counties/Pages/FindACounty.aspx|access-date=June 7, 2011|title=Find a County|publisher=National Association of Counties}}</ref> It falls within the [[Cascadia (bioregion)|Cascadia bioregion]].<ref>{{cite web|url=https://www.cascadia-institute.org/|access-date=August 27, 2021|title=Boundaries|publisher=Cascadia Institute}}</ref>

Siskiyou County is in the [[Shasta Cascade]] region along the [[Oregon]] border. Because of its outdoor recreation, Mt. Shasta, McCloud River, and [[California Gold Rush|Gold Rush-era]] history, it is an important tourist destination within the state.{{Citation needed|reason=Opinions are not allowed.|date=September 2021}}

==History==
{{more citations needed section|date=September 2013}}
Many Native American peoples including the [https://native-land.ca/ Confederated Tribes of Siletz Indians, Modoc, Cayuse, Umatilla and Walla Walla and Shasta], share geography with Siskiyou County and have lived in the area for millennia prior to colonization. Siskiyou County was created on March 22, 1852, from parts of [[Shasta County, California|Shasta]] and [[Klamath County, California|Klamath]] Counties, and named after the [[Siskiyou Mountains|Siskiyou mountain range]]. Parts of the county's territory were given to [[Modoc County, California|Modoc County]] in 1855.

The county is the site of the central section of the [[Siskiyou Trail]], which ran between California's [[Central Valley (California)|Central Valley]] and the [[Pacific Northwest]]. The Siskiyou Trail followed indigenous footpaths from Native People who share the geography with Siskikyou county, and was extended by [[Hudson's Bay Company]] [[Animal trapping|trapper]]s in the 1830s. Its length was increased by "[[California gold rush#Forty-niners|Forty-Niners]]" during the [[California gold rush]].

After the discovery of an important gold strike near today's [[Yreka, California]], in 1851, colonizers flooded the area. This was described in detail by [[Joaquin Miller]] in his semi-autobiographical novel ''Life Amongst the Modocs.''

In the mid-1880s, the construction of the [[Central Pacific Railroad]] along the Siskiyou Trail brought the first wave of tourism. Visitors were drawn by the county's many [[Upper Soda Springs|summer resorts]], and to hunt or fish. The [[Southern Pacific Railroad|Southern Pacific railroad]], the successor to the Central Pacific, called its rail line "The Road of A Thousand Wonders."

In the early 1940s, Siskiyou County was home to the semi-serious [[Jefferson (Pacific state)|State of Jefferson]] movement, which sought to create a new state from several counties of northern California and the adjoining counties of southern Oregon. The movement has seen a revival in recent years.

The origin of the word ''Siskiyou'' is not known. It may be a [[Chinook Jargon]] word for a "bob-tailed horse" (ultimately originating in [[Cree language|Cree]]),<ref>{{cite book|isbn=9780520389670|page=236|title=California Indian Languages |last1=Golla |first1=Victor |date=February 2022 |publisher=Univ of California Press }}</ref> or as was argued before the State Senate in 1852, from the French ''Six Cailloux'' (six stones), a name given to a ford on the [[Umpqua River]] by [[Michel Laframboise]] and his Hudson's Bay Company trappers in 1832. Others claim the ''Six Cailloux'' name was appropriated by [[Stephen Meek]], another Hudson's Bay Company trapper who discovered Scott Valley, for a crossing on the [[Klamath River]] near [[Hornbrook, California|Hornbrook]].

The county is home to the [[Black Bear Ranch]], a commune started in 1968 with the slogan "Free Land for free people."

On September 4, 2013, the Siskiyou County Board of Supervisors voted 4 to 1 to secede from the State of California.<ref>"Siskiyou County supervisors vote to pursue seceding from state", The Record Searchlight, redding.com, September 4, 2013</ref>

==Geography==
[[File:Mossbrae falls.jpg|thumb|right|260px|[[Mossbrae Falls]], near [[Dunsmuir, California]] ]]

According to the [[U.S. Census Bureau]], the county has a total area of {{convert|6347|sqmi}}, of which {{convert|6278|sqmi}} is land and {{convert|69|sqmi}}, or 1.1%, is water.<ref name="GR1">{{cite web|url=https://www.census.gov/geographies/reference-files/time-series/geo/gazetteer-files.html|publisher=[[United States Census Bureau]]|access-date=April 23, 2011|date=February 12, 2011|title=US Gazetteer files: 2010, 2000, and 1990}}</ref> It is the fifth-largest county by area in California.{{citation needed|date=February 2018}}

Siskiyou County is geographically diverse. From towering [[Mount Shasta]] (elev. {{convert|14,179|ft|m|abbr=on|disp=semicolon}}) near the center of the county, to lakes and dense forests, as well as desert, chaparral, and memorable waterfalls, the county is home to world-famous trout-fishing rivers and streams, such as the [[Sacramento River|Sacramento]] and [[McCloud River|McCloud]] rivers. The county is dotted as well with lakes and reservoirs,<ref name=lakes>{{Cite web|url=https://www.fishingworks.com/california/siskiyou-ca/|archive-url=https://web.archive.org/web/20131029224349/http://www.fishingworks.com/lakes/california/siskiyou/|url-status=dead|title=Siskiyou Archives|archive-date=October 29, 2013|website=FishingWorks}}</ref> such as [[Castle Lake (California)|Castle Lake]] and [[Lake Siskiyou]]. Mount Shasta itself has a [[winter sports]] center. Pastoral [[Scott Valley]] in the western part of the county has many wide, tree-lined meadows, supporting large cattle ranches. The basins of northeastern Siskiyou County, including Butte Valley, Lower Klamath and Tule Lake basins, have some of the deepest and richest soils in the state, producing alfalfa, potatoes, horseradish, and brewing barley. Butte Valley nurseries are the leading source of premium strawberry plants in North America. Much of the county is densely forested with [[pine]], [[fir]], [[Calocedrus|incense-cedar]], [[oak]], and [[madrone]]; Siskiyou County is also home to the rare Baker's Cypress Tree, [[Cupressus bakeri]], which grows in only eleven scattered locations in the world, five of which are in Siskiyou County. 
The county's natural resources are most often used these days for skiing, snowboarding, [[hiking]], [[mountain biking]], [[camping]], and wilderness recreation, as historic logging practices have been largely discontinued due to Federal and State environmental regulations. The county's water is viewed as sufficiently pure and abundant that the county is a source of significant amounts of bottled water, distributed throughout the country. A large Crystal Geyser plant is at the base of Mt. Shasta, near Weed.

===Flora and fauna===
Substantial amounts of the county are forested within the Siskiyou and Cascade Ranges, including significant [[oak woodland]] and mixed [[conifer forest]]s. Siskiyou County is the northern extent of the range for [[California Buckeye]],<ref>[http://www.globaltwitcher.com/artspec_info.asp?thingid=82383 C.
