Grass Valley (Pershing and Humboldt counties, Nevada)

The north section of the valley is part of the southwest portion of Winnemucca on the Humboldt River.

Clear Creek flows down the valley center, north-northwesterly and joins the Humboldt at Rose Creek, Nevada, 10 miles (16 km) southwest of Winnemucca.

[3] Grass Valley trends north-northwest and is nestled between two mountain ranges on the Humboldt River's south.

[5] The valley narrows north and south to about 4 miles (6.4 km), but widens at the floodplain of the Humboldt River.

The center of the valley[6] is approximately just southwest of Clear Creek Ranch at the west foothills of the Sonoma Range.
