Wind Cave National Park Poster
Bison grazing in ponderosa grassland with a prairie dog on watch in the foreground. What's under the grass is stranger. One of the longest caves in the world runs beneath this prairie, lined with boxwork — thin blades of calcite standing out from the rock in a honeycomb of fins, like the walls grew their own scaffolding. Ninety-five percent of all the boxwork ever found anywhere is down there.
