The North Fork of the Humboldt River is an approximately 70miles long tributary of the Humboldt River in northern Elko County, Nevada.
The river has its headwaters on the north slopes of McAfee Peak in the Independence Mountains of northeastern Nevada. It quickly exits the mountains and turns southward for approximately 25miles, joining its waters with numerous other streams. Making a sharp bend to the east, it flows through a small gorge called Devil's Gap and then combines with Beaver Creek before resuming its southward course. The river, often with no more than a trickle of water left after its long journey through the dry hills of north-central Elko County, finally flows into the main branch of the Humboldt River about 15miles northeast of the city of Elko.
The North Fork watershed is remote. Some mining activity in the area took place in about 1870, followed by cattle ranching and later sheep ranching in the 1890s. Problems of overgrazing and erosion in the Independence Mountains, which form the headwaters of the North Fork, prompted the federal government to establish the Independence Forest Reserve in 1906. This reserve has since been incorporated into the Mountain City Ranger District of the Humboldt-Toiyabe National Forest.[1]
