Description 

Frog Rock is the most obvious big chunk of limestone that can be seen from Bozeman, towering over Bozeman Pass on the south side of I-90. For years there were major access issues which have been resolved as long as folks are respectful and follow the signage.
The rock is Madison limestone/dolomite outcropping here in features up to 400' high. Pockets abound from shallow dish monos to huge incut huecos. Routes clean up well with a bit of scrubbing and traffic.
There are sunny routes, shady routes and most in-between. This area is a bit higher and much of the hillside is north facing, so is nice and cool generally. The only print guide is Dockins', which doesn't cover the newer routes around Servus, so chances are you'll not have too much company.

Getting There 

Take the Trail Creek Exit off I-90 (west of Bozeman Pass proper). Once on the south side of the interstate, go east to the Chestnut Mountain parking lot (~1/4 mile from the exit). The trail crosses private property for 0.6 miles, then take a right after another 0.6 miles at a signed post, then another 0.9 miles to the main area (~2.1 miles each way).

Panthalassa 5.11 6c+ 23 VIII- 23 E4 5c  MT : Frog Rock : East Crags
FA 5/20/2012. Four main pitches, one belay move and another really short pitch to get to the tippy top. 5.7, 5.11, 5.9, 5.10, 5.5 (15'). Big pockets. The crux is boulder problem length. The first pitch is an approach pitch. The belay move pitch (The Cockles Traverse) has even worse rock than the first or the actual summit. The rest of the climb is solid. The summit is very cool, but the last 5-10' of the wall the rock quality seriously deteriorates. There are good bolts on the summit ri...[more]   Browse More Classics in MT

The approach is bikeable for those who are interested. Going up is a bit brutal but it does make for a fun multisport day!
