About
Delta.3.5 is a bouldering problem located in the Alpha-Beta-Gamma-Delta Block near Delta, Colorado, on the Western Slope. The problem is situated on a 10-foot (3 m) boulder with GPS coordinates 38.91, -104.829. The route starts on the same slab as Delta.3 but moves up and left, avoiding the arete to climb a clean, solid, vertical rail characterized by tension climbing until reaching the lip. The difficulty is classified as moderate. Access requires caution due to a painful block at the base, making a crash pad recommended. Parking is available on site, and pets are permitted. The area is accessible year-round, though recent flood damage has reopened the site with a note to evaluate rock integrity for safety. The first ascent was recorded by NH.
