This trail follows old logging roads built atop long abandoned mining roads used to access the quartz and copper from the Rainy Mine, worked intermittently until 1957. Today the road is lined with second-generation hemlock and cedar, now shouldering out the alder and huckleberry that took over after clear cutting in the 1970s, making for a pleasant—albeit challenging—road hike.
Beginning at the end of Forest Road 56, just before the Taylor River Bridge, veer to the left at a signed juncture pointing toward Quartz Creek along the often muddy and rocky roadbed. The sharply pointed top of Mt. Garfield can be seen to the east, as well as Quartz Mountain across the valley. At roughly two miles a spur veers up to the right toward Rooster Mountain; keep left to continue on to the Blethen Lakes. As the route progresses, the quality of the road/trail progressively degrades. Occasional blowdowns block the trail, and the creek crossings are not bridged, with the exception of a single log that spans one ravine.
The road ends and gives way to real trail at a creek roughly a half-mile from the first lake. Lower Blethen Lake is not overly impressive, but you’re almost guaranteed solitude. To reach the next lake, continue around the lakeshore and up the 500’ pass at the far end to reach Upper Blethen Lake and a close encounter with the craggy top of Bessemer Mountain. Enjoy the splendid isolation, and keep a watchful eye out for wildlife: rabbit, coyote and deer.
