This peak is not in the book. Also see the Owyhee Mountains Peaks List for all of the peaks in this range.
The Owyhee Mountains‘ northern escarpment facing the Snake River Plain runs from northwest to southeast. The middle stretch is known as the Silver City Range. The Silver City Range’s southeast end is at Toy Pass. Moving further to the southeast, the crest then climbs up to a second high point on the summit Toy Mountain. From this point the escarpment is cut by the Castle Creek drainage before it once again rises up to the the Rough Mountain group which includes Doyle Mountain..
Doyle Mountain is the highest summit north of Rough Mountain and sits in a commanding position between Castle Creek and Birch Creek. The peak is studded with granite outcroppings and treeless. Access to the peak is surprisingly good. From Murphy, Idaho drive 19.0 miles east on ID-78. Turn south onto the Oreana Loop Road. Follow this paved road for 4.0 miles where the paved road makes a 90 degree turn and heads west. At this point the gravel, signed Oreana Cut Off Road (some maps call this road the Poison Creek Road) continues south. Follow this road for 10.0 miles where there is a four way junction. Turn right on the road that runs southwest up Birch Creek. Keep right when the road turns due south following Birch Creek. You will reach a pass due south of Doyle Mountain in 7.0 miles. The seven mile climb is on a surprisingly good road that has been graded at times. (If you are comimg from Grandview, you can take Missle Base Road to the junction with the Oreana Cutt Off Road and the Birch Creek Road.)
From the saddle a 4WD road heads north for a short distance where there is plenty of room to park. The route now becomes a trail. Follow the trail until it starts to descend. Leave the trail at this point and climb up to the summit on easy slopes. Class 2. USGS Pixley Basin
