Kittitas County (/ˈkɪtɪtæs/) is acounty located in theU.S. state ofWashington. At the2020 census, its population was 44,337.[1] Itscounty seat and largest city isEllensburg.[2] The county was created in November 1883 when it was carved out ofYakima County.[3] Kittitas County comprises the Ellensburg, Washington,Micropolitan Statistical Area.
There are numerous interpretations of the county's name, which is from the language of theYakama Nation. According to one source, it "has been said to mean everything from 'whitechalk' to 'shale rock' to 'shoal people' to 'land of plenty'". Mostanthropologists andhistorians concede that each interpretation has some validity depending upon the particulardialect spoken.[4]
The county was organized in November 1883 by the Washington Territorial Legislature, carved from the northern part ofYakima County.
Indigenous peoples known as Kittitas (or Upper Yakima) occupied the lands along theYakima River for hundreds of years before the present era. The Kittitas Valley was a traditional gathering place for tribes east of the Cascades.
White settlers began pouring into the Kittitas Valley in the late 1850s. Their arrival forced dislocation and displacement of the native inhabitants, who were eventually forced into theYakama Indian Reservation. White settlers introduced livestock raising, crop farming, dairying, logging, lumber processing, and mining. The abundant grassland and the generally-favorable terrain made beef and cattle production become the county's mainstay. That was assisted by the introduction of railways into the area and the large-scale irrigation systems introduced in the 1930s.
Wheat planting in Kittitas Valley began in 1868. The county's first flour mill was established near Ellensburg in 1873. Production of alfalfa was also seen from the county's early days.
Lumber extraction was an important county activity from its early days, mostly in the west end. Logging camps were established near the county's three largest lakes (Cle Elum, Kachess, Keechelus).
Mining for coal and minerals was established by the mid-1880s.[5]
The southeastern corner of the county is part of the U.S. Army'sYakima Training Center.
According to theUnited States Census Bureau, the county has a total area of 2,333 square miles (6,040 km2), of which 2,297 square miles (5,950 km2) is land and 36 square miles (93 km2) (1.5%) is water.[6] The highest point in the county isMount Daniel at 7,959 feet (2,426 m) above mean sea level.
There are a variety of species represented within Kittitas County. These include a diversity of grasses, herbs, trees, birds, mammals and amphibians. The genus of ricegrass known asOryzopsis was one of the earliest grasses classified within the county.[7] Among the amphibian species found are theCascades frog and therough-skinned newt, the latter being a common far western USA taxon; in fact, examples ofneoteny have been found in individual newts of this species within the county.[8]
