The Pfeifferhorn, at 11,326 feet (3,452 meters), is a majestic peak located east of Salt Lake City, Utah in the Wasatch mountain range. Its easy access, proximity to alpine lakes and short trail make it a popular hike year-round. The easiest route involves moderately steep hiking and a short 3rd class section. Since only a few mountains in the Wasatch are higher than Pfeifferhorn, the rewards are breathtaking views of the Salt Lake valley and surrounding mountains. Also, mountain goats can be frequently seen above upper Red Pine Lake.

The Pfeifferhorn is recorded as "Little Matterhorn" on USGS maps. The mountain is known as the Pfeifferhorn, in honor of Chuck Pfeiffer, a local climber who was the leader of the Wasatch Club.
