Jewel Cave National Monument
Immerse yourself in one of the longest caves in the world. With over 215 miles of mapped and surveyed passages, this underground wilderness appeals to human curiosity. Its splendor is revealed through fragile formations and glimpses of brilliant color. Its maze of passages lures explorers, and its scientific wealth remains a mystery. This resource is truly a jewel in the National Park Service.Photo: "Although a "slower" time of year, the winter season offers some of the best scenery of the ponderosa pine forest." - NPS Photo / Bradley Block
