Yellowstone River hydraulics define the landscape of Treasure County on this recent survey, where the river's path is flanked by an extensive network of irrigation infrastructure. The small settlement of Myers serves as a focal point near the southern bank, situated just west of Guys Bluffs and south of the braided channels surrounding Howrey Island. The fertile valley floor, known as Pease Bottom, is interlaced with vital water management systems including the Hysham Main Canal, Yellowstone Canal, and Box Elder Ditch. To the north, the terrain transitions into a more arid landscape of intermittent drainages like Cowen Creek and deep incisions such as Antelope Coulee, showing the contrast between the managed riverfront and the open plains. Long-established ranch roads, including Ingomar Rd and Mission Valley Rd, connect the scattered homesteads across this Big Sky territory.
