Carson River in the context of "Lyon County, Nevada"

Washo or Washoe (/ˈwɒ.ʃoʊ/; endonym wá꞉šiw ʔítlu) is an endangered Native American language isolate spoken by the Washo on the California–Nevada border in the drainages of the Truckee and Carson Rivers, especially around Lake Tahoe. While there were only 20 elderly native speakers of Washo as of 2011, since 1994 there had been a small immersion school that has produced a number of moderately fluent younger speakers. The immersion school has since closed its doors and the language program operates through the Cultural Resource Department for the Washoe Tribe. The language remains very endangered; however, there has been a renaissance in the language revitalization movement as many of the students who attended the original immersion school have become teachers.

Ethnographic Washo speakers belonged to the Great Basin culture area and they were the only non-Numic group of that area. The language has borrowed from the neighboring Uto-Aztecan, Maiduan and Miwokan languages and is connected to both the Great Basin and Northern California sprachbunds.

State Route 89 (SR 89) is a state highway in the U.S. state of California that travels in the north–south direction, serving as a major thoroughfare for many mountain communities in the Sierra Nevada and the Cascade Range. It starts from U.S. Route 395 near Topaz Lake, winding its way up to the 8,314-foot (2,534 m) Monitor Pass, down to the Carson River, and up again over the 7,740-foot (2,359 m) Luther Pass. From that point on, the route generally loses elevation on its way past Lake Tahoe, through Tahoe and Plumas National Forests until Lake Almanor. For roughly 9 miles (14 km) the route forms a concurrency with State Route 36. SR 89 then ascends to the 5,753-foot (1,754 m) Morgan Summit. After it enters Lassen Volcanic National Park it continues to gain elevation until it reaches its highest point through an unnamed pass in the middle of Lassen Peak and Bumpass Mountain. While SR 89 is signed as a continuous route through the park, the portion inside Lassen Volcanic National Park is federally maintained and is not included in the state route logs. The road then descends out of the park and heads northwest, finally terminating at Interstate 5 at the foot of Mount Shasta at around 3,600 feet (1,100 m).

The West Fork Carson River is a major tributary of the Carson River, about 35 miles (56 km) long, in Alpine County, California, and Douglas County, Nevada, in the United States.

It rises in the Sierra Nevada of California, at Lost Lakes near Carson Pass in the Mokelumne Wilderness of Humboldt-Toiyabe National Forest. It flows north into Hope Valley where it is joined by SR 88 (Carson Pass Highway), which closely follows the river as it travels toward Nevada. At the northern end of the valley it turns east, flowing through a gorge, before emerging from the mountains near Woodfords. From there it flows north, into the Carson Valley of Nevada, where it joins with the East Fork Carson River at Genoa to form the Carson River.
