Learn about Idaho’s thousand-mile, long-distance Idaho Centennial Trail, which runs from the Nevada border to Canada, on Thursday night.

The program starts at 5:30 p.m. Thursday, April 18, at Ketchum’s Community library. It offers a look at the trail, which begins near Murphy Hot Springs crosses the Snake River near Glenns Ferry, snakes its way through the mountains of central Idaho, skirts the Selway River and proceeds through the Cabinet and Selkirk Mountains enroute to Canada.

It crosses the Oregon Trail, the Lewis and Clark Trail and the Nez Perce Trail, as it works its way through 11 national forests and Bureau of Land Management land, the Sawtooth Wilderness, the Frank Church-River of No Return Wilderness and the Selway-Bitterroot Wilderness.

Thursday’s presenter will be Clay Jacobson, who calls himself an Idaho Centennial Trail ambassador. He hiked the trail in 2015 and since has been working with the Idaho Trails Association to address the trail’s maintenance issues with boots-on-the-ground trail work as the trail is hard to find in spots and rough in others.
