Chockstone Tower is an ultra classic tower in Palisades State Park. Many fun routes up it. Routes vary from the "West Slab Route"5.3 to "Aloha" 5.12. Great Dihedral is " The Bitch " 5.8-5.9? This tower also has some fun face climbs. Split Rock Creek roars less than 20 feet away so as you climb all you can really hear is the river a fun intense climb.
