Many look at the moderate 5.9 grade and believe that this route will be a walk in the park. The reality is that Epi -- as the locals call it -- is a route that includes significant difficulties that one doesn't often encounter on a regular day out at the crags. Indeed, the route is known for one major feature: a long 5.9 chimney system.
The first third of Epinephrine is dominated by chimneys. These chimneys are incredibly smooth inside. Some have even equated them to glass. It often feels that the inch at a time gains inside the chimneys might be lost at any moment from a mild slip or fall. Difficult passage inside the chimneys are exacerbated by the fact that the route is so big that a pack is absolutely necessary. To move through the chimneys one must drag their pack between their legs.
The last third of the route climbs a massive mid-fifth class ramp. One climbs pitch after pitch after pitch of easy terrain that slowly allows altitude to be attained. Finally after traversing an exposed tree ledge, one finds himself at the base of an easy scramble which leads to the top of Velvet Peak.
Red Rock Canyon is famous for its moderate (5.6-5.9) multi-pitch routes. There are literally hundreds of them. At the upper end of moderate climbing, Epinephrine stands out as a spectacular and unforgettable adventure.
