2020 Map of Orinoco

About this map

The Yellowstone River anchors this central Montana landscape, cutting a wide path through Rosebud County. Small settlements and specialized landmarks like Orinoco and Flynn sit along the northern bank, while the landing strip at Tillitt Field serves the local ranching and agricultural community south of the water. The map documents a classic Western transport corridor, showing the alignment of Old US Hwy 10 running parallel to the river. Tributaries such as Little Porcupine Cr and Horse Cr drain the surrounding heights, leading down toward the breaks of Wildcat Coulee. Notable local thoroughfares, including Cartersville Rd and Quarter Horse Rd, provide a window into the rural road network and land divisions that have long defined this river-bottom economy.
