Reed and Harper are exploring Mammoth Cave National Park, and they want to share with you everything they've learned about cave formations, ancient cave dwellers, and the endangered Gray Bat. For a one-time purchase, read about their adventures, find your way out of Reed's cave maze, color the postcard, and put the sticker somewhere you can show off your love for Mammoth Cave! 

Includes one double-sided letter, one activity sheet, one postcard, and one sticker.
