Trail of the Coeur d'Alenes
From Wikipedia, the free encyclopedia

The Trail of the Coeur d'Alenes is a bike path which follows the old Union Pacific Railroad right-of-way from Mullan, a mountain mining town near the Montana border, to Plummer, a town on the prairie near the Washington border. More than 72 miles of paved path takes you from high mountain splendor, through the historic Silver Valley, into the chain lakes region, along the shore of Lake Coeur d'Alene, over the Chatcolet Bridge to Heyburn State Park, and finally climbs to the Palouse prairie. You can continue along a bike path in Washington that will eventually lead to Spokane.
A remarkably well outfitted bike path, the Trail of the Coeur d'Alenes includes camping facilities and rest areas regularly. The trail leads through protected marsh lands, offering the cyclist a glimpse of eagle and osprey nests, moose, elk, and a variety of ducks and other wildlife, as well as some rare species of wildflowers and accompanying butterflies as a result of the age-old soot from the old railroad.
The trail is not only a recreational facility, but also a solution to environmental problems left behind by the silver mining industry. Silver was discovered in the valley around 1884, and a rail line was built to access the mines around 1888. Much of the rock in the railbed was either waste rock from mines, or tailings containing heavy metals. The railbed also got contaminated with spillage. To remediate these environmental problems, the Union Pacific Railroad, U.S. Government, the State of Idaho, and the Coeur d'Alene Tribe partnered up to build a trail. The thick asphalt and the gravel barriers on the sides of the trail provide a permanent cap on the waste and isolate contaminants.
