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


On the left side of the Sheep Skull Crags formation there is an orange pillar of sandstone. On the right side of this pillar is a wide chimney with a large chockstone wedged into place. Intestinal Flu climbs this chimney. There is an optional belay position (slings) at about fifty feet up, on top of the chockstone. Once past that position swing out left past a roof and up the offwidth crack. Belay at the top of the crack at some fixed slings.

Breaking the climb up into two pitches might be a good idea in order to avoid heinous rope drag.

Descend by rappelling from the slings with one 60 meter rope, or continue up with third class scrambling to the top of the cliff and walk off right.


Lots of wide gear is needed. Consider bringing two #4s and one #5 in Camalot C4 or equivalent. A green Big Bro might help, too.

To me the line seemed to climb/squeeze under both chockstones, eventually exiting the bat cave into the wide crack. The second chockstone is a lot longer and is the tightest, darkest, sandiest tunnel I've done in RR... classic!. Not for the claustrophobic/overweight. The tat anchors on top are total garbage so I'd recommend venturing a little further up and trending right to find a bolted anchor. We rapped here with two 60m's.

A hoot! Fortunately the bad rock on this route is in the first 5 feet. Super safe and interesting. We thought the tunnel was tight but not terrible, and I'm not super skinny. Anyone of reasonable size ought to be able to do it.
