===Exploration and early settlement===
The [[Lewis and Clark Expedition]] entered Idaho on August 12, 1805, at Lemhi Pass in present-day Lemhi County.

For [[Sacagawea|Sacajawea]], their guide and interpreter, the Lemhi Valley was her birthplace and her brother was the Chief of the Lemhi band. Clark went out to scout the expedition's route. Within a month, travel down the Salmon and Snake Rivers was ruled out and the expedition headed for [[Lolo Pass (Idaho–Montana)|Lolo Pass]] on the Bitterroot Range.<ref>{{cite web|title=Idaho State Historical Society Reference Series: The Lewis and Clark Trail Across Idaho|url=https://history.idaho.gov/sites/default/files/uploads/reference-series/0049.pdf |archive-url=https://web.archive.org/web/20120503181228/http://www.history.idaho.gov/sites/default/files/uploads/reference-series/0049.pdf |archive-date=May 3, 2012 |url-status=live|access-date=February 24, 2017}}</ref> Michael Bourdon of the [[Hudson's Bay Company]] established the Lemhi Valley as a base of trapping operations in 1822.

Mormon settlers established Fort Lemhi from 1855 to 1858. The settlement was withdrawn after a native attack on the settlement. The first gold miners ventured into Lemhi County in 1862, with miners working the main Salmon River all the way from Salmon down to Slate Creek.<ref>{{cite web|title=Idaho State Historical Society Reference Series: EXPLORATION AND SETTLEMENT OF SALMON RIVER|url=https://history.idaho.gov/sites/default/files/uploads/reference-series/0242.pdf |archive-url=https://web.archive.org/web/20120503185932/http://www.history.idaho.gov/sites/default/files/uploads/reference-series/0242.pdf |archive-date=May 3, 2012 |url-status=live|publisher=Idaho State Historical Society|access-date=February 24, 2017}}</ref>
