Event Description:
Donaldson's Woods and Mitchell Karst Plain "Walk amoung your elders: a hike through one of the nicest old growth forests in Indiana"

This special hike celebrates Division of Nature Preserves 50th anniversary!

Donaldson's Woods: This undisturbed old-growth woods is recognized by botanists as one of the most impressive stands of the original forest remaining in Indiana. This woods is classified as a western mesophytic forest type because it is intermediate between beech-maple and oak-hickory types. However, studies indicate that beech and maple are assuming greater importance. An unusual feature of the woods is the high percentage of white oaks. This region of the state is rich in karst features such as caves and sinkholes. Much of the run-off from the woods drains through sinkholes, rather than surface streams.

Mitchell Sinkhole Plain: This example of classic karst terrain consists of a very pronounced sinkhole plain that borders the entrenched valley of Mill Creek. The area is dominated by an abundance of sinkholes in various states of activity; many quickly swallow rainwater whereas others are plugged and remain ponded for short time periods. The natural opening and collapse of small caverns throughout exemplify the very dynamic nature of this landscape. This portion of Spring Mill appears to represent the largest single block of undisturbed sinkhole plain in a natural forest community remaining in Indiana.

These preserves are located in this State Park and are marked on the park map available at the gate house or park office.
