A plan to connect a hiking and biking trail to Mount Rushmore National Memorial is facing a tall challenge.
South Dakota Game, Fish and Parks is working to extend George S. Mickelson Trail to Mount Rushmore, but the 566-foot vertical ascent from the trail's current end to the memorial is presenting a problem to the department.
The department wants to make sure the trail extension won't be too steep for the average person to walk on.
The state has appropriated $500,000 to help kickoff the project, but construction won't begin before 2016.
Nedved says an option is to build an elevated boardwalk that would run parallel to U.S. Highway 244 just past the memorial boundary.
