Memorial Day Cave
Since its descovery in the year 2000, exploration in Memorial Day Cave has pushed the surveyed length of the cave to over 5 miles. Memorial Day Cave is not open to the public nor the caving community at large, however qualified cavers are invited to lend their assistance to the ongoing survey effort. Persons wishing to participate in this survey project are directed to contact the cave manager.
