Caldron Linn, or Cauldron Linn, also known as Star Falls, is a waterfall on the Snake River in Jerome County and Twin Falls County of southern Idaho.

[1][2] Caldron Linn was a key site of the Overland Party of the Pacific Fur Company, an expedition to the Pacific Ocean led by Wilson Price Hunt.

The churning waters of the falls inspired the expedition to abandon the river and continue on land to the Pacific.

East of present-day Murtaugh and South of Hazelton, the waterfall was added to the National Register of Historic Places in 1972 for its role in the expedition.
