St. Olaf volcano

The St. Olaf volcano threatened to erupt in 1952. At the time, some Shriners (posing as Druid priests in town for the opening of Stonehengeland) said they could stop the eruption if they could sacrifice the town's dumbest virgin. They told Rose Nylund that the only way to prevent the eruption was for her to crawl through their legs, up the volcano, while they gave her a birthday wax.
