Leaf Hills Moraines

"[1] Through their full extent in Otter Tail County, the hills have steeply sloped sides covered by prairies and deciduous forests, primarily maple and oak.

It is composed of a huge volume of morainic drift up to 350 feet (107 m) thick, overlain with thin sandy soil as well as rocks and boulders.

[2] The hills' outline is not regular, but erratic, and in many places the range is broken by rivers, streams, and Minnesota's famous lakes.

Pekan Peak (unofficial name) in Section 32, Folden Township, Otter Tail County, Minnesota, discovered by John Sandy in February 2022, at coordinates 46°11′54.744″ N 95°30′4.248″ W (DMS), Latitude 46.19854 Longitude -95.50118 (DD), has an elevation of 1,800.05 feet (548.66 meters), measured by LiDAR (Light Detection and Ranging) technology.

Due to their steepness and the abundance of fieldstone and boulders, the hills were found by pioneers to be generally unsuitable for plowing but well suited for raising and grazing livestock.
