This panorama was shot during June 2004 on the edge of a prairie depression found on the preserve. These 'prairie potholes' may have been formed by a variety of factors. Some were caused by glacial recession. Others were formed by bison rolling in the wet mud of a depression, causing further erosion. After these 'bison wallows' were deep enough, they were more likely to collect water. This played a very important role for tall grass prairie fauna looking for a source of water on the open plains.

Dominant flora seen in this panorama are Big bluestem (Andropogon gerardii), Canada goldenrod (Solidago canadensis), and Western snowberry (Symphoricarpos occidentalis).
