About this map

Chippewa National Forest encompasses much of this glacial landscape in Cass County, defined by a dense network of lakes and drainage systems. Large water bodies like Thunder Lake and Big Rice Lake are central features, surrounded by smaller basins such as Pug Hole Lake, Coffin Lake, and Blue Bill Lake. The mapping shows a recreation-oriented infrastructure with numerous localized access points, including Deer Haven Bay Dr NE and Arrow-Peninsula Dr NE.

Transport through the timber and wetlands is facilitated by CO Hwy 7 and specialized routes like the Eagle Country GIA Snowmobile T. The drainage pattern is led by the Willow River in the northeast corner and Spring Br in the southwest, illustrating the low-lying hydrologic connectivity of the region. This survey captures a modern look at the forest's development, where residential roads like Michaud Lake Dr NE interface with protected natural areas.
