Description 

This is a small crag compared to others in this general area, but it is the highest in elevation. This rock forms a summit cap on the Western ridge above the North side of Fern Canyon. From the top, you look back on a nice view down into town and to the West into the mountains. The angle from which you view all the other crags is almost disorienting.

The rock here is generally compact smooth and solid, with one notable exception (Almond Joy, 5.8+) and is given to slab and face climbing. The non east-face routes here range in height from 30' to 70' and in difficulty from 5.3 to 5.13.

The south face gets sun most of the day, and the West face in the afternoon.

To descend this rock, downclimb about 1/2 way down the East face on the South end to a point where it is possible to step left around a corner and onto the ground, or climb to reach the anchors on one of the several sport routes and rap off.

Getting There 

Head up the Fern Canyon trail passing Fern Canyon and the Nebel Horn Ridge, eventually arriving at a flat "pass" with loose gravel as a base (very little soil) and braided trails. To the right (North) there is a stubby-looking summit tower, and this is the Mars Block. You are looking at the shortest face, the South. The harder climbing is all on the West side, the easier climbing faces you on one of the two south-facing aspects, and the tallest stuff is only revealed by walking under it to the West.

I haven't climbed this route, but having looked at it, from top to bottom, it looks thin and sustained. The obvious line is to follow the bolts along the vertical north-facing wall, near the arĂȘte at the west end of the wall. I saw an old "bail biner" at the 4th or 5th bolt, perhaps where the crux lies. The wall is rather exposed to wind from the west and north....[more]   Browse More Classics in CO
