Mammoth Cave

We're in one of those three states where they meet at the Cumberland Gap National Historic Park campground. We luxuriated in hot showers here where no coins were needed. We worked up a little sweat earlier in the day on the Domes and Drips hike in Mammoth Cave. The tour dropped three-hundred steps down into an old dry underground river channel which we followed until getting to an area with active water. With water added, the stalactites, stalagmites, and columns came into view and the oohs and ahhs started. I didn't realize that it is the longest identified cave system in the world with over 400 miles of caverns mapped.

I enjoyed seeing the 1888 train that once brought tourists to the cave. The steam engine is only half the size of the combination passenger/baggage car it pulled.

This may be our last night on the road for this trip as we are only 6 hours from home. Of course, we may find something interesting to delay us...
