Above: The view south from the top of Far Mountain, northeast of Fairbanks. Smoke rises far in the distance from a wildfire more than 100 miles south.
Far Mountain Traverse is roughly a 28-mile hike that starts and ends at Chena Hot Springs. The loop has a total elevation gain around 15,000 feet, with a summit of more than 4000 feet — one of the highest peaks in the surrounding area.
In addition to considerable mileage: rock fields, granite tors, smoke clouds from wildfires, mild bushwhacking and a lot of mosquitos. All standard Alaska backcountry.
One thought I had during the hike was to reach Far Mountain, then pack raft out. I found a very in-depth blog post about just such an adventure at Go Play Outside, a fun Alaska excursion blog with extensive information. A hike a raft is doable.
