Rehabilitate Cave Trails: New Entrance to Frozen Niagara
The purpose of the project is to provide safer walking surfaces for park visitors, staff, and volunteers; reduce or eliminate the impact of lint and dust on delicate cave resources; and protect cave resources by keeping visitors on defined trails and away from sensitive cave resources. This work supplements the improvements previously planned for nine tour routes between the Historic Entrance and the Frozen Niagara Entrance.
The National Park Service (NPS) proposes to replace and upgrade deteriorated cave trail assets along the Frozen Niagara Route (1,605 lf), the New Entrance Route (600 lf), and the Drapery Room (100 lf) with new sustainable assets. This includes construction of a hardened trail surface, installation of 18" high lint curb along each side of all trails; replace existing handrails with stainless steel handrails, and the upgrade/reconstruction of 8 steps of steps along these routes of the Frozen Niagra Trail, Mammoth Cave National Park, Mammoth Cave Kentucky.
