2020 Map of Calypso
USGS Topo · Published 2020About this map
The Yellowstone River carves a deep arc through this section of Prairie County, Montana, defining the local geography and transportation corridors. Along its southern bank, the settlement of Calypso sits near the bend where the Milwaukee Rd and W Old Hwy 10 parallel the water. The landscape is marked by a complex network of drainages including Sullivan Cr, Lost Boy Cr, and Cherry Cr, which feed into the main river valley. Notable terrain features like Sheridan Butte rise above the surrounding coulees and creeks, while Wolf Rapids indicates the river's dynamic character in this reach. The presence of Calypso Spring suggests the importance of water sources in this arid environment, where land is still organized by the Public Land Survey System townships like t12n r50e.
