Rolling Hillsides
Perry Township’s ridge top vistas, gently sloped valleys, wandering streams, rock outcrops, and
rugged cliffs create a picturesque landscape. Located within the Driftless Area (an area of
southwestern Wisconsin not covered by glaciers), Perry was not leveled, scoured, or blanketed
with glacial deposits from the last continental ice sheets.
Instead, Perry is a plateau formed by deposits of ancient seas with streams
slowly carving narrow valleys in a pattern resembling the branches of trees.

Rock Outcroppings
As elsewhere in the Driftless Area, a number of open and shaded cliff
communities occur in Perry Township. These areas can be as large as a tall vertical rock face and
as small as a single rocky ledge. Cliff communities support plants that are adapted to cliff life
and that are generally not found anywhere else. These plants - of which ferns are the most
common example - thrive with very little soil by sending roots far into the rock in search of water
and nutrients.

Streams
Perry’s surface waters consist of permanent and temporary streams. No natural lakes are
found here. The average
depth of these streams is six inches, and the average width is three to four feet. In the absence of
disturbance, bottom types are usually gravel or rubble because stream gradient discourages
settling of silt. The streams are prone to flooding, however, because of their steep gradients and
rapid runoff across the hilly topography. |
