Wind Cave Room - Boxwork Chimney
NPS Photo by Bill Holmes
Herb and Jan Conn and Dave Schnute first looked down this drop on August 23, 1964, but did not survey it until August 30, 1966. The name is derived from the first 40-foot drop in this route to the lower level of Wind Cave which is very tight and boxwork-lined. Two more drops following this go down an additional 40-60 feet. Although the last two drops are not boxwork-lined, the three drops are known collectively as Boxwork Chimney.
