(Washington, D.C.) -- Crater Lake National Park has a new company running concessions. Following months of complaints from staff and federal lawmakers, the National Park Service has approved ExplorUS to run hospitality that includes lodging, food and beverage services, retail operations at gift shops and boat tours. The previous provider - Aramark - faced criticism over employee working conditions and facility maintenance. Most visitor services will open for the season at Crater Lake in mid-May.
