In the early 1900s mining dominated the mountains south of Great Falls and countless small settlements filled the coulees and gulches. Raynesford was a railroad town to service those mines. Raynesford is just north of Sluice Boxes State Park. Soaring cliffs and precipitous ledges mark the Belt Creek Canyon as it slices out of the Little Belt Mountains and winds toward the town of Belt. Sluice Boxes State Park consists of the northern most 8 miles of the Belt Creek canyon.
