Trinity Peak

Elevation: 11,050 ft
Prominence: 800

Climbing and access information for Trinity Peak is found on page 267. Livingston Douglas has provided additional information on the peak’s south ridge and Brett Sergenian climbed the peak’s east ridge. Updated 2018


This peak is located on the ridgeline that connects Grouse Creek Mountain with the main crest. It is not easy to spot from the Pahsimeroi valley but it is beautiful peak with an enjoyable route to the summit. The peak has three high points. Livingston Douglas points out that:

“Trinity Peak has three high points on the narrow ridge that is its summit area. The Grouse Creek Mountain quadrangle puts them all at 11,040’+. So which one is highest? If you climb the southeast ridge, as I did on 7/11/14, you’ll first reach the South Summit. The South Summit has 2 ridge points approximately 100’ apart. These two points are very close in height. My Suunto altimeter, which expresses altitude in 10-foot increments, found them to be of equal height. Visually, however, the northernmost of these 2 points is slightly higher. I viewed each of these points from each other to make this determination. But is the North Summit higher? Visually, the North Summit appears to be slightly lower. The North Summit is about ¼ mile to the N of the South Summit on the narrow summit ridge crest. You must drop 70’ to a small notch to make this 8-minute ridge traverse. The North Summit measures at 10’-20’ lower according to Mr. Altimeter. When viewed from the North Summit, the South Summit appears to be slightly higher.”

“My conclusion is that, of the three points of “equal height”, the middle one is highest and is the northernmost of the 2 points on the South Summit. It lies about 100’ north of the southernmost point on the narrow summit ridge crest. There were no cairns on any of these ridge points.“

Livingston Douglas made the first known descent of the peak’s south ridge in 2014 as part of a ridge traverse from Trinity to Hope. His route is set out below.

South Ridge Route, Class 2 by Livingston Douglas

Date of Climb (7/11/14). This is the first leg of a ridge traverse from the summit of Trinity Peak to the summit of Peak 11010/Hope Peak (see the Northwest Ridge Route of Hope Peak for a complete description of this traverse). The South Ridge is easy class 2 on broken scree. Goat trails will help you on this route. The South Ridge begins at the 10,460′ saddle just N of Point 10721; it ends on the true summit of Trinity Peak, which is the northernmost of the two ridge outcrops that comprise the south summit area of the peak.

East Ridge, Class 2+ by Brett Sergenian 

According to my map I could catch the east ridge a couple miles from the end of the road.  After going around a small lake, I decided to gain the ridge to avoid loose scree to the west.  Just below 10,000′ I navigated around through some snow before following the snow free ridge.  There were a few sections where I had to use my hands for balance but it was easy climbing to the ridge.  The traverse between the two peaks looked relatively easy except for one section below the summit so I decided to play it by ear.  Once at the middle summit I was not sure if I was on the high point so I wandered over to the north summit.  According to my phone it was 15 feet lower.
