"The existing revolving door was constructed in 1992 and after twenty years it has deteriorated to the point where there are numerous air leaks," said park superintendent Vidal Davila. "This project proposes to replace the revolving door with an airlock structure that can accommodate a 40-person tour and create a two-door airlock system that would reduce airflow in and out of the cave through this man-made entrance."
The public is invited to attend an informal open house at the Wind Cave National Park Visitor Center on Tuesday, February 21, from 4 p.m. to 7 p.m. to discuss the plan with park staff and to comment on the alternatives.
