I seem to remember a pretty good area on the south end of North Gateway rock just across from the Spire. Just to the left of where that #3 is in the photo. That was in 1990 so this could be the peyote talking...

There are a lot of names carved into the rock where you describe and there isn't any bouldering allowed there, because they want to preserve the names.

You might be thinking of the Wall of Winter Warmth, or something like that. It's a steep, thin slab that gets bouldered a fair amount. From the closed area, head 200 feet west, or 100 feet west from the Cowboy Boot Crack area. The traverse is supposed to go at 5.9, but I'd say it's harder with hold breakage. Fun area.
