Trail Overview

FS 85, beginning north of Rocker at just over 5,500 feet, is a single-lane trail that goes through several private land parcels before ascending to 6,900 feet. There are very minimal opportunities for camping south of the intersection with FS 608. Going west, staying on FS 85, opens up with a two-lane road into larger fields with multiple easy-moderate rated trails. FS 5165 leads south into multiple other forks where more camping, hiking, and potential hunting opportunities exist. Descending on the north-facing slope, there are logging efforts before returning to the Interstate 90 exit through other private parcels.

Difficulty

This trail is relatively easy. There were some mud holes and tight corners, but overall, the main trail was easy despite being tight and having a quick elevation gain. Roads forking off of FS 85 are significantly more challenging. Even in the winter, when snow filled the trail past 6,000 feet, the trail was passable. The intersection at FS 85 going west was plowed, but south of this intersection was not plowed.

Rode the first portion from Butte to the Four Corners intersection. Looped back through American Gulch. Dry. Mixed packed sand/gravel, loose gravel, protruding rocks. A few downed trees poking into the road. A few ruts in the sand from wash out. Nice ride through trees and meadows. Easy tackled by a beginner on and ADV/Dirt bike. Nice paved twisty lead up from Butte on Browns Gulch.
