Ice Box (later renamed by some ... Jurassic Park) is a nice secluded area with a good concentration of moderate cracks and even some sport routes. The routes are all short, most are only about 50-80 feet long, but the rock quality is excellent so it is worth a visit.
Dirt roads reopened as of June 2014 Details

Getting There

Park at the lower parking lot and follow the Turtle Lake trail as it winds along the base of the main cliffs. Pass Holy Saturday (obvious large rock formation near the trail) and locate an unmarked climber's trail after about a half mile. Hike up and over Jurassic Pass and descend steeply to the cliff.

On the approach to Jurassic Park, on the left side, approximately 75 yards to the east of recombination mutation, there are several (easy-looking) bolted slab climbs. These climbs don't appear on the site nor in the H & T book, and the bolts look shiny/new. Does anyone know who bolted these or their grades?

EDIT: After investigation, I found this to be the Old Folk's Wall. May 28, 2012
Yeah, I know, but those ACs guys are still out there and not just at Vedauwoo. I just like to point the ACs out once in a while. By the way, thanks for attaching a name to your comment. Jul 2, 2009
Way to take a stand on an argument that is 7 years old. Jun 30, 2009
Several comments. 1. Great place to climb, nice hike that takes you away from waiting in line to climb on Walt's Wall. 2. Instead of bickering about the names, why doesn't someone provide the history and correct names. This "Colorado" vs. "Wyoming" climber thing is beyond old. 3. This is America, all are entitled to their opinions. Anyone who doesn't sign their name to their comments or opinions is a faceless instigator that just stirs people up. Enough of the Anonymous Coward stuff although the title aptly describes them. Jun 30, 2009

That sounds awesome. I am coming out in a few weeks to learn the ways of the offwidth (and history, if someone is giving dissertations on how what now is once was). Jun 30, 2008

This is a great place for both those who are well versed in crack and those who are looking to build their skills. Recombination Mutation and Sore-O-Pod aka Spatial Juxtaposition are both excellent intros to crack and all of the climbs here are short enough to top. Jul 5, 2007
Has anyone actually climbed in this area? If not a sugest you give it a try, it is quit rewarding. Story is as told. Jul 30, 2003
I have read every Vedauwoo guide book available in the Laramie Library, and the history of Vedauwoo climbing, and the climbs themselves, have been poorly documented, so all this debate over who is ignorant is getting old. Sep 21, 2002
Long before Mud In Your Eye and Lichen Lung were climbed, this area was loosely referred to as Ice Box, as some locals know. When Piana freed Mud, he sure didn't call the entire area Mud - why? There were nasty battles being fought even back then (ask around), and there were many unclimbed lines still there which remained so until the early '90's. Ethics, history, somebody needs a primer in both. Sep 20, 2002
Long before Mud was ever climbed this place was called Ice Box. You should at least know that much. Wonder why Mud never stuck either. Sep 20, 2002
I'm sure you Wyoming locals were bummed climbing shoes didn't come in extra high tops. Sep 17, 2002
Interesting history. Maybe ignorance of the past is part of all this 'dumbing-down' of rockclimbing that's happening. Is 'attention-deficit-disorder' the excuse? Sep 17, 2002
Actually I think this area was originally known as the "Sheep" area, shortened for ease of local pronounciation from the namesake climb "Sheep's One Thing, but Them Boys Crossed the Line". The naked, freesoloing FAs subsequently disappeared without a trace. Sep 16, 2002
This area is called Mud in your Eye, after its namesake climb. A couple ego maniacs from Colorado decided to write a book and rename most of these routes after a movie. All these routes had been done for years, some named and others unnamed. Seems to me ethical climbers do not name routes unless they did the FA or rename routes unless did the 1st free ascent. Seems to me that ethical climbers don't rename areas unless they discovered the place. Heel and Toe, get out of Vedauwoo. Sep 16, 2002
