From Elko Daily Free Press:
In 2017, a gray wolf was spotted in Nevada for the first time in nearly 100 years. It was at Fox Mountain, west of the Black Rock Desert and probably wandered east from California’s Shasta pack. The last Nevada sighting before that was in 1922, near Elko County’s Gold Creek. Nevada has probably always been poor wolf habitat and never carried a large population.
Yet Nevada is literally surrounded by wolf populations. The closest is a wolf pack roughly 40 miles from Reno. (All these mileages are very approximate.) So more of these predators are likely to wander into Nevada in the future.
