Photos: Kartchner Caverns

For 10 years, the Kartchner Caverns' Big Room has been open to visitors from mid-October through mid-April, when its resident bats migrate elsewhere. The Big Room complements the Throne Room, which opened to visitors in 1999. Arizona State Parks celebrated the Big Room’s anniversary earlier this month with special speakers and presentations, including the dedication of the Kartchner Caverns Underground Microbiology Exhibit.

Look through the gallery to view photos of Kartchner Caverns since its discovery up to its public opening in 1999.
