Anyone have any beta on the obscure original line refered to in the Hubble and Rolofson guide? It just indicates that the route goes up the center to the hanging forest. No rating or topo nor does it say whether or not the route tops out or to decend from the hanging forest.
I think you might be referring to the Wiggins-Doucette Route 5.10 R. Ken Trout's guide shows this route and a couple of other crack routes. Kevin Stricker is a good source for Big Rock info. I have not climbed it yet but hope to soon. I have only looked at it from the west.
I rope solo'ed a variation of what I thought was Doucette/Wiggins a few years ago. Mostly just looking for an easy way to the top of Big Rock. The climb was pretty un-remarkable with the standard popcorn granite and crumbling cracks common in the inner Platte. Below is a brief description:
Head up the draw between the two buttresses of Big Rock until it gets steep enough to rope up. There is a major chimney system on the right that is not the route. Diagonal left along a shallow ramp and get to more 4th class scrambling. There was a fixed rope hanging on the face to the left that I used for pro and kept the gear packed. Climb up towards a hand and fist crack with a steep wide section you can layback on a flexing flake or grovel through. The crack peters out and there was an old stopper I penji'ed left to the next crack, and followed it free at about 9+?. The left crack was pretty good, and I stretched the rope to a huge block wedged in the crack (face climbed around left side). The next pitch takes you to the hanging forest, easy climbing past tons of gravel and loose blocks. After a close encounter with a big block I was ready to be done with the climb, I headed up through the hanging forest working my way right around a small buttress to a final pitch of 5.5? slab to the top. The Doucette-Wiggins heads up left from the forest and looked like it had some good climbing.
