It Finally Happened. So says the e-mail I received...


As you enter Clear Creek Canyon, just before Tunnel 1, several ice flows appear extending from an aqueduct on the south side of the road on the opposite side of Clear Creek. Due to the low elevation and dependence upon the state of repair of the aqueduct, these flows do not form regularly. When they do, they provide some excellent local ice climbing. There are at least three other very short smears with ice-bouldering potential farter down the trail behind Tunnel 1. The details of these are not listed here. Some of these climbs start directly from Clear Creek. Climb these when the creek is well-frozen otherwise lower/rap from the top.

At the moment, another climb located just to the west of Tunnel 1 is included in this subarea.

Getting There 

About 1 mile from the intersection of CO Hwy 93 and US 6, up the Clear Creek Canyon several ice climbs are visible originating from a wooden Aqueduct on the south (left) side of the road. Park in front of Tunnel 1 and hike down a small, signed hiking trail that follows the old roadbed. Cross on the frozen creek to the climbs.

Various flows have formed across from the 1st tunnel over the year. 2000-01 was a bonus year, but they were gone pretty quickly. Hopefully, these will form again. Upstream from the tunnel is a bridge. Walk downstream along aqueduct carefully. There are various areas to walk down.Described L->R are some of these: In the photo: 1. Short WI2-3 flow; 2.

Since 2000-01 season, the aqueduct has been repaired and it is unlikely these gems will ever form again.
