The Grey Cliffs are the tall bands of limestone towering above the Grey Cliff Lodge and Alaskan Inn on the North side of Ogden Canyon. They are high up away from the road and over 100 feet tall, hosting many single pitch aid and free routes and a few two-pitch outings. Routes have been done on these walls probably as far back as the 50s and 60's. Rock quality is inconsistent, some say horrendous. This may be limestone but this is not a sport-climbing zone. The rock is unique from the lime South in American Fork and North in Logan in that it is able to be traditionally protected. Water has scoured grooves, pockets and runnels into the sharp stone and seams/thin cracks abound. Few climbers frequent the limestone therefore rotten rock prevails especially on the higher more difficult to access routes. Each area begins with a band of deteriorating blocky shale and mudstone. This band can extend from anywhere between 2 feet to 30 feet, but always eventually gives way to the sharper but more compact grey-blue limestone above. The features here are crazy. Because the approach is steep, loose and treeish the crowds are kept at bay and therefore this area is not an ideal candidate for yet another sport crag. If you want a well-protected sport crag with sharp holds and vertical to overhanging routes, just cross the canyon, there is a "killer" one in view. The grey cliffs, requiring a bit more effort to access, deserve a different ethic. Bolts exist at anchor points but only occasionally mid-route. Pins abound, young and old. Longer run-outs and heads-up climbing give the area character. Morning till evening sun. Stunning views of the entire canyon as both valleys open up in the distance. This area is divided onto several sub-areas: Drillbit Wall and the approach boulders(5 minute approach), Facerock (aka hummingbird wall-30 minutes), And the Grey Cliffs themselves (East, West, Upper, and Lower- 45+ minutes). Tread lightly and don't disturb land owners.
