Excerpt
Buffalo Horn Pass straddles the Gallatin Range Divide between the Yellowstone and Gallatin Rivers. The pass lies between the northwest corner of Yellowstone National Park and Ramshorn Peak in the 26,000-acre Gallatin Petrified Forest. Millions of years ago, volcanic mudflows smothered and preserved ancient tropical forests in this fascinating area. Exposed by erosion, petrified stumps and logs are abundant throughout the landscape. The hike begins from Tom Miner Campground and parallels Trail Creek, continuing past the creeks headwaters to a circular meadow at the 8,523-foot summit of Buffalo Horn Pass. Atop the ridge are the petrified forest and a 4-way junction, with connections to the Gallatin Canyon, Ramshorn Peak, and Yellowstone National Park.
