The Owyhee Mountains are discussed on Pages 343-347 of the book. The website contains significant updates and expands on the book’s content. See the Owyhee Mountains Peaks List for all of the peaks in this range.
The Owyhee Mountains are an incredible mountain uplands that are still mostly unknown to most climbers. The range was forced up by the Owyhee Batholith 40 million years ago. Some geologists believe that Owyhee granite is part of the Idaho Batholith, isolated from the main batholith by the passage of the Yellowstone hotspot. Much of the range’s granite is covered by Miocene rhyolite that erupted as a result of a meteorite impact 17 million years ago. The range is surrounded by the younger volcanic rocks of the Snake River Plain and is still covered in places by extensive deposits of older sedimentary rock. Where Owyhee granite has been exposed to the surface, it has formed impressive outcroppings and an occasional dome.

There is a lot of private property interspersed throughout the range. Please read Private Property, the Idaho Code, Trespassing and You by Margo Mandella to help you understand the complications caused by private property.

Most climbers and peakbaggers ignore the range because of its long history of mining and its attraction to off-road vehicle enthusiasts. Yes, there are many mining roads and you may run into a dirt bike, but the range is vast. Three wilderness areas are enclosed within its boundaries and the mountains beyond the Silver City area are wild and usually empty. There are 141 peaks (either named or unnamed) in the range. See The Owyhee Mountain Peak list page for all of the peaks. You can also click on the Owyhee Mountains entry for all peaks that I have updated since the book came out and, of course, the book has a lot of additional information on the range.
Access Updates: Owyhee Mountains Access is covered on Pages 345-347 of the book. The following updates expand on the book. Additional access information is found on many of the website’s peak pages.
Owyhee Uplands Back Country Byway
The old mining town of Silver City sits in a basin on the south side of the range’s highest peaks. During the Summer and during hunting season, the area is often crowded on weekends.
Silver City, in the heart of the Owyhee Mountains, is as isolated as any Idaho town.
Evidence of the mining era can be found throughout the range.

This granite dome is located near Silver City. Despite its fine lines, I have not heard of any rock climbers trying to climb its faces.
The Owyhee Mountains encompass many impressive canyons. This formation is in Hardtrigger Canyon.
The range even has its own granite badlands.

Access in the range outside of the area around Silver City can be problematic, as many roads are not well maintained and private property blocks a lot of areas. No Trespassing signs need to be heeded as the law is usually enforced.

Owyhee terrain varies greatly over the ranges expanse. The highest peaks are clustered around Silver City.
