About this map

Union Lake and Lake Sarah dominate the glacial landscape of Polk County in this modern survey, which documents a region defined by its water and agriculture. The terrain is dotted with numerous small lakes and basins including Maltrud Lake, Crooked Lake, and Matson Lake, while the Sand Hill River cuts across the southeastern corner. This area serves as a significant recreational and rural hub, evidenced by the Union Lake Sarah Campground and Farmers Union Park Campground situated along the northern lake shores.

Local genealogy and history are well-represented by several burial grounds serving the surrounding townships, such as Bailey Cemetery, Lima Cemetery, and the Union Lake Cemetery. Transport and utility are highlighted by the presence of Hemmingsen Airport and a grid of secondary roads like County Hwy-210 and County Hwy-1. The map reveals a transition between dense lakeside activity and the broader agricultural tracts that characterize the Red River Valley hinterlands.
