Denrock 

HI there-

Don't climb at Denrock much, but when I went last I saw nothing even close to 100ft. Highball bouldering or short short top-rope. Many TR anchors are being bolted. Kinda dirty (in a ghetto way) and super contrived much like Lincoln Woods though the rock is different. Maybe enough for a weekend if you climb hard (past V8 or so) but if your like me you'll find some projects, especially with variants. Not destination worthy but if your in the area or passing through on the way to P-tuck or Lincoln worth checking out.

New to mtn prjct, maybe next time I'm down that way I'll take some photos.

No face at Den Rock exceeds 30 feet, Desperado being the highest. Most of the crags are around 20-25. The rock is pegmatite, a sharp granite with lots of crystals. In 2007 a large number of glue-in anchors were installed, protecting most routes on the six main crags. This makes TRing much easier, as there is little natural pro at the top and very few trees. The bouldering referred to in the description is spread out but of good quality. Below the Building Blocks face are two boulders, each with several moderate lowball problems. The Remnants and City Dump areas are short enough (12-15 and 15-20 feet respectively) to be bouldered. City Dump especially is known as a fine training boulder, as it overhangs and is covered with good crimps and edges. Many eliminates can be made here, allegedly ranging in difficulty up to V9. Above the City Park section is an 8-10 foot slabby boulder with short moderate problems.

I agree with Duncan that the tallest face is probably 30 feet max.

If someone can update the map link, it points to the wrong location. The crags are located around 42.679975,-71.136571
