The Ruby Mountains are a mountain range, primarily located within Elko County with a small extension into White Pine County, in Nevada, United States. Most of the range is included within the Humboldt-Toiyabe National Forest. The range reaches a maximum elevation of 11387ft on the summit of Ruby Dome. To the north is Secret Pass and the East Humboldt Range, and from there the Rubies run south-southwest for about. To the east lies Ruby Valley, and to the west lie Huntington and Lamoille Valleys. The Ruby Mountains are the only known range of an introduced bird, the Himalayan snowcock, in North America.The 'Rubies' were named after the garnets found by early explorers. The central core of the range shows extensive evidence of glaciation during recent ice ages, including U-shaped canyons, moraines, hanging valleys, and steeply carved granite mountains, cliffs, and cirques. All of these features can be seen from 12-mile Lamoille Canyon Road, a National Forest Scenic Byway which traverses Lamoille Canyon, entering the range near the town of Lamoille.
