There are a ton of new bolts here. I have never seen a soul here. The rock is good where it's good and scary where it's bad. Stick to the friction. Do not test the waters with any jugs.

Known FA - Robby Baker, 1972.

Half Dome Crack aka Party Time 5.9 5c 17 VI 17 HVS 5a  CO : South Platte : ... : Little Half Dome
Rotten rock, wide cracks, and runout friction make this route less than perfect. On the other hand, many of the old low altitude and easily approached Platte crags are closed now, for example; Sphinx, Squat, and Snake Buttress. Half Dome Crack will work the muscles needed for both Utah Desert and Yosemite crack sufferage. The dome gets good sun during the training seasons of late winter and early spring. A quiet weekday spent along the South Fork of the South Platte River almost ma...[more]   Browse More Classics in CO

In 2002, I bolted the black streak on right side, .11+/.12-. Also added anchor and a couple bolts to route on front right side, one to protect a 5.10 mantle move and one up near top. Also added a slab variation to 5.9 and one bolt to protect moves off anchors on upper pitch. I don't who added two pitch slab route on left side of formation. Good route, but could use one more bolt to protect crux on last moves of second pitch. 5.11.

Either Robby or Lee Marsh, or maybe both did the first ascent of the wide crack. Shitty rock quality. Anyone else noticed that the best quality rock in the Platte tends to have the longest walk from the road?

We had to bail on a Light D off of one of the last bolts before the anchors on P.1 of the "Unknown .10d" on Little Half Dome.
