Beautiful big wall on Hollow Top Peak can be seen ...
This area has some potential for bouldering close to Bozeman. Most of the climbing potential is in the boulder fields along the North side of the Cataract Lake/Mason Lake road on both BLM and National Forest land. Mason Lake proper can be accessed by a 1.3 mile trail and offers beautiful views of Hollow Top peak.
Drive through the town of Pony and make the next right going up a steep dirt road. Staying straight instead will take you to the North Willow Trailhead where there is a pit toilet and access trails to Hollow Top Lake and Peak. Shortly after turning right you will pass the "Public Access through Private Land" sign. Please respect the private property and stay on this road until passing the "BLM Public Lands" sign after about a mile. Boulder fields can be found along the North side of road. After another half mile or so you will come to Y, left takes you to the Mason Lake trail. The trail is 1.3 miles to the lake and is open to ATV's.

There's about 30 established problems above Mason Lake, mostly in the large talus field. There's another dozen or so established around Upper Mason Lake (below the granite big wall) as well. Definitely a lot of potential around Cataract Reservoir, but the rock quality isn't quite as good as the upper stuff.
