Siskiyou

The Siskiyou Mountains arc between the watersheds of the Klamath River to the south and the Rogue River to the north. Their western slopes receive heavy rain and winter snow, while the eastern country is drier. Indigenous trails followed the river valleys and crossed the mountains, linking the Sacramento and Willamette valleys. Fur traders used the route in the early nineteenth century; one account connects the name Siskiyou with a bob-tailed horse lost during Alexander McLeod's journey over the pass in 1829.
