You won’t believe what’s going on 650 feet underneath those Kansas wheat fields (about the height of the Gateway Arch in St. Louis from top to bottom.)
It only takes 70 seconds going straight down an elevator shaft to see one of the 8 Wonders of Kansas.
A mining museum — the Kansas Underground Salt Museum in Hutchinson, Kansas.
A working salt mine — although museum visitors are not anywhere near any blasting or ongoing work.
And Batman costumes — because at a constant 68 degrees and 45% relative humidity in 325 feet of solid salt, the already-mined sections are a perfect home for the Underground Vaults and Storage company’s long-term records and artifact storage, including a bizarre variety of Hollywood’s goodies and film masters.
