This route is actually on the far right side of the Thunderbird Wall, but sits directly across from the route Smokin' The Rock (5.10b) which is why it's listed here.
Easy moves on a slab gain the base of a steep headwall with an obvious hueco. Undercling the hueco, make a long reach to a distant edge and then finish up past a short section of crack.
The crux is fairly reachy, and shorter climbers may find the route to be harder than indicated or simply not be able to make the requisite reach.
