This unit is located in south central Montana and directly to the south of Big Timber. This unit is basically made up of three main drainages, Deer Creek, Main Boulder and the West Boulder. Most of the moose are located in the Main Boulder. There are a few moose scattered in the other drainages along the foothills and in the riparian areas.

Moose numbers are lower than historic levels but currently stable and may be slightly increasing. After the wolf introduction moose numbers declined and tag numbers were reduced. With two bull tags now the harvest has been 50% for the last three years and an average of 22 days per harvest. There is a chance to kill a mature bull in the 40 inch category.
