History
The Lewis and Clark Expedition crossed the Continental Divide at Lemhi Pass, to the southeast of Salmon. They followed the Salmon River through the present site of the city, then ascended the north fork of the river, at the present-day town named after the confluence, to cross into present-day Montana near Lost Trail Pass. The sole female in the party, Sacagawea, was born in the Lemhi Valley near Salmon. The Sacajawea Interpretive, Cultural and Educational Center was opened in Salmon in August 2003. From 1910 to 1939, Salmon was the western terminus of the now-defunct Gilmore and Pittsburgh Railroad. File:Salmon idaho owl club.jpg|The Owl Club in downtown Salmon, Idaho.
