Might this be the most famous alpine face of the whole Rockies? Certainly very few pieces of rock in North America can rival with the density of high quality climbing. Also remarkable is the variety of routes, from class 4 scrambles and 5.6 alpine outings to hardcore almost-never-in-condition WI6+ ice smears and 5.13c and 5.14a big walls (unsurprisingly, both with FFA from Tommy Caldwell). You can even find mossy A4 nail-ups if that's your thing.
Though the Diamond is the main show, the poster also features both lower and upper east walls and Chasm View Wall, as well as a little bit of the north face. With 104 routes, it is the most exhaustive poster of the east face ever made!
