A distinctive right-leaning arch forms the most distinctive feature of this route's lower pitches. Two starts were done. Either climb along the arch from left to right (5.7) or climb directly up to the midpoint of the arch from below (5.8, no pro), in both cases reaching a stance belay. Continue right along the arch for a full ropelength (5.8) to a ledge belay. Continue straight up for a full pitch featuring a left-facing slim flake (5.8). Two easier slab pitches (5.7, 5.6) lead to the top.

The East Face of Alpaca is a distinct dome at the southern end of the northeast face, not far north of the col with Llama Peak. Obvious when approaching from Coldwater River and visible in profile from Zupjok. Either bushwack up from the last switchback on Coldwater Road to the route (1 hour +) or descend from the ridgeline near Llama Peak.
