About this map

Upper Glaston Lake and the Glass Lindsay Lakes Lower Reservoir dominate the central basin of this Sweet Grass County landscape. The area is defined by a series of drainage systems, including Sweet Grass Cr, Rock Cr, and the descriptively named Dead Beaver Cr, which flow through a topography ranging from the open flats near the reservoirs to the elevations of the Franklin Hills in the west.

Remote ranching and access roads such as Rupert Rd, Cremer Rd, and Otter Creek Rd trace the sectional boundaries of Township 3 and 4 North, providing a glimpse into the modern rural infrastructure of this Montana high-country. Local landmarks like Cottonwood Springs suggest the importance of water sources in this environment, while the network of creeks like Cayuse Cr and Alkali Cr illustrates the complex hydrology that feeds the larger lake system.
