2011 Map of Cat Creek NW

About this map

Blood Creek and Cottonwood Creek dominate this 2011 survey of Petroleum County, tracing the intricate drainage patterns of the Missouri River breaks. The landscape is defined by the stark, eroded terrain of central Montana, where watercourses have carved deep, winding paths through the plains. The map reveals the isolation of this region, showing a network of secondary and local roads that navigate between the creek beds and upland flats. While few man-made landmarks appear, the topographic detail provided by the U.S. Geological Survey highlights the extreme relief of the coulees and ridges typical of the Big Dry country, providing a clear record of the area's physical geography in the early 21st century.
