The belay position on Coronary Bypass.

RAIN AND WET ROCK The sandstone in Red Rocks is fragile and is very easily damaged when it is wet. MORE INFO >>>


A pleasant route. This could probably be done in a single pitch if you scramble up a bit to establish your initial belay. But two pitches works out well and reduces rope drag.

Climb up and right to a belay stance beneath the right edge of the hanging block. Climb past a small overhang and continue up the varnished face to the big ledge. A bolted rap station is on the right side of this ledge.


Start at the left base of the Hanging Block Buttress.

The first pitch is easier than 5.5 and only worthwhile to gain the much more interesting second pitch which is harder than 5.5. Rapping from the top anchors down to the start of Chocolate Sunday is possible with two 60 meter ropes.

Most of this climb is 5.5, but it has some interesting features that are worth noting. Good protection on the first pitch is sparse due to horizontally fractured rock and need to avoid rope drag. Second pitch involves pulling a small roof or a delicate short traverse right of the belay. A second thin spot on this pitch is 5.5+++! Compared to, for example, Crooked Crack (5.6) in Willow Springs, much more challenging. New trad leaders be careful.
