Vacation 2000, Oregon Caves National Monument

Inside the Oregon Caves National Monument.
The formations look big in these pictures, but most of them are about 4 feet tall. Huge cavern, with part of my tour group for scale.
Fast-growing stalagmite, near the center of the picture. The same huge cavern, this time with night exposure. About 30 vertical feet of jellyfish formations.
View from the ridge above the caves.
