The Bear River winds through the southeastern corner of Idaho, defining a valley carved between the Preuss Range and the Sheep Creek Hills. This landscape is heavily shaped by early 20th-century irrigation efforts, visible in the intricate network of the Montpelier Preston Canal, Black Otter Canal, and Ream Crockett Canal. These waterways supported the development of small ranching communities like Pegram and Harer, which sit along the valley floor near the river's edge.
