Trapper Peak is located north of Monument Peak. It is a cone shaped summit which can be reached after a bumpy drive and a short hike. USGS Trapper Peak

Access

Roads of varying quality lead all the way to the base of Trapper Peak. The peak can be reached from I-84 at Exit 182 or from Oakley, Idaho. [(A)(1j or (B)(1) at page 347] Google Maps works well when you are approaching from the freeway. Just search for Trapper Peak, Cassia County. This approach starts on the Rock Creek Road, FS-515 which is paved until just past the Magic Mountain Ski Area. The unpaved road is improved and although bumpy in places, passable when dry to passenger cars with good clearance until it reaches FS-2197 in 6.3 miles from the ski resort.

A 4WD is necessary to drive FS-2197 from FS-538. The road is particularly bad on the north side of Point 7801. It is 1.6 miles to the start of the hike up the peak.

Western Slopes, Class 1+

Park at 1.6 miles at a junction. Walk down hill a short distance where an overgrown path leads north through the trees. Follow this path through the trees to the open ridge beyond. Turn right on an over grown track that leads east and up to the summit. It is 0.4 miles with 285 feet of elevation gain from the parking spot to the summit.

Trapper Peak by Livingston Douglas

Date of Climb:  September 26, 2019

Trapper Peak is the 2nd highest peak in the South Hills. Amazingly, this beautiful, pyramidal-shaped peak is an unranked point on the North Ridge of Monument Peak, the South Hills’ highest mountain. Monument Peak lies only 2 miles to the south of Trapper Peak. Trapper Peak is home to a herd of elk, both cows and bulls. I heard, then saw, a few cow elk high on the East Face on this cold September morning. Better yet, I saw a couple of bull elk near the summit. This is a very special place. The views from the summit are spectacular. Trapper Peak is, hands down, my favorite peak in the South Hills.

Access

Park at the [signed] junction of FSR-533 and FST-174. This junction is located about a mile north of the junction of FSR-533 and FSR-538. The elevation here is 7,275 feet.

Southeast Shoulder, Class 2

From the road junction, hike briefly W (perhaps 0.1 mile or so) up FST-174 (an ATV road) to get past a section of thick aspens on the S face of Trapper Peak. Look for an opening through the aspens to begin the climb up the Southeast Shoulder. Once past the aspen grove, work your way up the face/shoulder through gapped sagebrush. Higher up, the shoulder is better defined and the climb becomes smooth sailing on easy short scrub/grass. The views of the valley floor open up as the early-morning sun warms your chilled exterior. In 20 minutes or so, you’ll be standing on the summit.

The summit of Trapper Peak had no summit cairn and no obvious USGS BM, as it is supposed to have. I did find a small piece of rebar sticking out of the ground in the summit area and that was all. The summit high point is about 50-75 feet NW of the rebar protrusion. I built a modest cairn atop the ground boulder that is on the high point of this peak. The views of the surrounding peaks and valleys/canyons are magnificent. Take some time to enjoy them.

USGS Map Errors on Trapper Peak:

The USGS map shows a trail crossing west-to-east across the summit. No such trail exists any longer. The USGS map shows the elevation of Trapper Peak as 7,892 feet and Mr. Altimeter confirmed that figure with a 7,890-foot assessment (my Casio Altimeter Watch rounds off to the nearest 5 feet). However, the USGS topo map shows the highest contour line at 7,840 feet, making the 7,892-foot figure impossible. I believe that the USGS map is in error and is missing the 7,880-foot contour line. Unfortunately, the Trapper Peak quadrangle has several of these types of errors.
