A cave in Harmony, Minnesota, Niagara Cave is filed here for what the record attaches to it. The cave with a 60-foot underground waterfall on the Iowa line.

The site is open to visitors.

Niagara Cave is the cave the pigs found — the 1924 discovery when three of Phil Todd's pigs fell through a sinkhole seventy-five feet into the limestone and their squeals led the searchers to the cavern. The pigs survived; the cave they found had a 60-foot underground waterfall that gave it the name.
The cave is Minnesota's underground waterfall — the 62-foot cascade in the limestone, the wedding chapel where 400 couples have married beside it, and the stream that cut the passages through the Ordovician seafloor. It's one of only two caves in the state open to the public.
The tours have run since 1934 — the Cremer-Tekippe-Flynn development that made it a roadside attraction with billboards across the country, the three families who've owned it since, and the waterfall that's still running. The file keeps the cave's origin: the pigs, the waterfall, and the Minnesota cavern that named itself for Niagara.
Niagara Cave is the archive's waterfall file — the 1924 pig discovery, the 62-foot underground cascade, and the wedding chapel that's been marrying people beside it for ninety years.

WHY THIS FILE MATTERS
Niagara Cave is the archive's pig file — the cave found because livestock fell in, the waterfall that gave it the name, and the chapel that's made it a wedding destination.
A cave found by pigs keeps its waterfall — the file's suggestion being that Niagara's hold is the cascade: the 62 feet of underground water, the chapel beside it, and the discovery that started with three pigs on a ledge.
