Captain Lewis undertook a few "scientific" experiments at the Burning Bluffs, including both tasting the minerals and inhaling the sulfurous smoke. Apparently, his experiments made him sick, and he spent a few days recovering.

So, what's the cause of this South Dakota geological wonder (although some may find it an oddity instead)? The Carlile Shale that lines the banks of the Missouri River contains a large amount of iron sulfide. When the iron sulfide reacts with oxygen and water, it releases heat, creating smoke.

In addition to iron sulfide, Carlile Shale also contains clay minerals, which retain water...which, in turn, spurs the exothermic reaction even more. This is one of the most incredible and fascinating natural wonders in South Dakota.

This geological oddity is increasingly rare but is usually seen near the Platte-Winner Bridge, and anywhere between Fort Randall and Chamberlain.
