2014 Map of Sigma

About this map

The N Br Manistee River and the N Br Boardman River define the hydrography of this northern Michigan landscape, where the headwaters of these distinct drainage systems nearly meet. Small rural settlements like Sigma and Angling are situated along the river valley, while Cotton and O'Neil occupy the higher ground to the west. This map illustrates the transition from the lake-dotted terrain of Crawford Lake and Lake Placid in the north to the more structured grid of rural roads such as Cool Rd SE and Kniss Rd SE further south. Genealogists and local historians will find family and community history at Excelsior Cem and Oliver Cem, which serve the dispersed farmsteads and small clusters of residences that have long characterized the Oliver Township area.
