Strata- Middle Fork of Salmon River

The Middle Fork of the Salmon River in Idaho flows through the heart of the Frank Church River of No Return Wilderness. This is the ancestral home of the Tukudeka Sheep Eaters a hunter-gatherer people who lived along the river until the Sheepeater Indian War of 1879.

His loss to Julius Caesar at the epic Battle of Alesia marked the conclusion of the Roman conquest of Gaul, a major turning point in the history of Europe.
