Description
The Mount Blackmore Trail is a long, beautiful dayhike to a 10,154-foot mountaintop in the Hyalite Recreation Area. Mount Blackmore was named by Ferdinand Hayden, an early geologist and surveyor of the Rocky Mountains with the U.S. Geological Survey. The peak sports a jam-packed site with views of Hyalite Reservoir below, other peaks in the Gallatin Range, and the Bridger and Crazy Mountain Ranges far to the north. Begin the hike to Mount Blackmore on wide trails frequently used by locals in the winter for groomed cross-country skiing. The first mile of the hike goes through thick forest and is well signed to help avoid confusion on the trail. At the third (and largest) junction, follow signage for Blackmore Lake. Early on you will encounter a large wildflower-laden meadow. Follow the trail along Blackmore Creek to Blackmore Lake, a popular fly-fishing spot for adventurous fishermen. From the lake the trail quickly gains elevation. In a few miles the trail opens up to a beautiful mountainside riddled with tough switchbacks and encouraging views. Briefly enter the trees once again, cross a small snow-fed creek, and walk onward to a vast, vivid-green cirque covered in tall grasses and spotted with wildflowers. Tread carefully on the few areas left with snow. At the saddle, hold on to hat and layer up! Wind speeds pick up here and can be chilly. Enjoy the unnamed peaks of Hyalite to the south and the massive 10,085-foot Elephant Mountain directly east. Continue west on the ridge to Mount Blackmore for a well-earned vista and break. Trails do not stay snow free for long. If you encounter hikers along the way with downhill skis or snowboards in tow, you may reconsider this hike if youare not planning a fast and thrilling descent from the top!
