There are many people responsible for the information found within these pages. The library staff at the Kentucky Library at Western Kentucky University in Bowling Green, Kentucky ranks among the best in supplying us with the finest sources of information on Mammoth Cave and the Kentucky Cave Region. For the past 10 years, it has been my primary choice when seeking information on the cave area. Other noted libraries include the Filson Historical Society in Louisville, Kentucky and the Ekstrom Library at the University of Louisville. Thanks to the staff at Mammoth Cave National Park who have inspired me since I was 11 years old with their first-class interpretation of the cave. Thanks to Mammoth Cave park ranger Charles DeCroix for the personal cave tours and for giving me a better understanding and appreciation of Mammoth Cave. Finally, a special thank you goes out to Mammoth Cave area historian Norman Warnell. If I ever had a question about Mammoth Cave, he always had an answer, and his knowledge of the cave area is truly remarkable.
