Join Manhattan Project National Historical Park rangers and REACH Museum educators on a free guided, 3.6-mile (5.8 km) round-trip moderate hike to the top of Candy Mountain on Saturday, May 16 from 9:00 am to 11:00 am Pacific time. There will be several stops along the trail up to the summit where rangers will share short histories about the events and people that shaped the mid-Columbia region. Hikers will move forward in time as the stops progress from the Ice Age Floods to the Manhattan Project and its legacies. Topics will include the Native Peoples who have lived here since time immemorial, the Lewis and Clark Expedition, the arrival of Christian missionaries, and the selection of Hanford for plutonium production during World War II. Hikers will gain 555 feet (170 m) of elevation as they hike to the top of Candy Mountain. Participants should be prepared to hike uphill, bring water and food, and plan for a variety of weather. Meet in the Candy Mountain trailhead parking lot by 8:45am for a 9:00am departure.
