Yorks Islands, River islands in Missouri River near Townsend, Montana, US.
Yorks Islands is a group of small islands that spread across the Missouri River floodplain, creating natural formations within the waterway about 4 miles south of Townsend. These scattered land masses form distinct structures in the river system.
The islands were documented by the Lewis and Clark Expedition in 1805 when they mapped them during their journey through Montana Territory. This marked an important point in the early survey and exploration of the western region.
The islands are named after York, an enslaved man who was part of the Lewis and Clark Expedition and played an important role in exploring the American West. Visitors sense this historical connection while moving through the quiet waterway and natural surroundings.
The fishing access site offers over 20 acres of space with boat launches and fishing spots along the Missouri River. Camping is available, and visitors should prepare for varying water levels and currents that change with the season.
The official name 'Yorks Islands' was not recognized by the U.S. Board on Geographic Names until 2000, nearly two centuries after they were first explored. This delayed recognition reflects how long it took for the contributions of York and other expedition members to receive formal acknowledgment.
