About
T-Rex Nail Boulder is a 15-foot boulder located on the Colorado Mesa University campus in Grand Junction, Colorado. The climbing problem is classified as moderate difficulty and is considered beginner-friendly. It is categorized as a deepwater solo, meaning climbers fall into water below rather than onto a crash pad. The boulder is part of a complex featuring three technical boulders situated near a fountain. Access requires a short Class 4 approach from the CMU parking lot at the university center. Parking is available on-site, and pets are permitted. The elevation is listed as 4,636 feet in the database, though one source cites 8,932 feet. Climbers should be aware of water levels, which can rise significantly during flood season.
