Square Rock

Colorado > Boulder > Flatirons > Central
Warning Access Issue: 2024 Crag Closures & Temporary Trail and Raptor Closures DetailsDrop down

Description

Cubic rock with several good routes. Some highball boulder problems exist on the W. face of this rock and some lines ranging from about 11-12d exist on the other side. TR setup is pretty easy.

Getting There

Take Broadway to Table Mesa and turn W. on Table Mesa. Follow Table Mesa all the way to NCAR and park at the NCAR lot. Now take the "NCAR Trail" along the nature walk along the rim of the hill. Look for a trail that cuts left and down the hill to some switchbacks. Follow this trail all the way to the water tower and continue left of the tower down to the Mesa Trail. Here, you will come to a junction with a Boulder Mountain Parks info/map board. Take the Mallory Cave Trail up the hill for a nice hike. You will see several signs for climbing access, but stay on this trail. When you come to the junction of the climbing access to Dinosaur Mountain, take a right up the hill, which is still the Mallory cave trail. Keep following the trail until you see a sign for climbing access to "Der Zerkel." You'll see the nice cliffs just up the hill. :)

[Hide Comment] All the anchor bolts on top of Square Rock as well as on Babyhorn have been replaced with Stainless Steel Fixe bolts. The old holes were used when possible and the rest were filled in and camouflaged with epoxy. This was done legally through the OSMP bolt replacement process. Enjoy. Aug 13, 2007
[Hide Comment] It is so messed up somebody is removing those hangers. I think and hope it is not a climber but some idiot stoner climbing the tree to burn on top of the rock. Time for glue ins! Sep 2, 2014
