Ecological Features & Diversity

Merry Lea is among the best-assembled land preserves in Indiana and contains a diverse group of Indiana ecosystems.

The 1,189-acre preserve contains a wonderful complex of lakes, wetlands, upland and lowland forests, oak savannas/woodlands, prairies, and meadows. Unique geological features include:

  • A glacial esker on the west side of the property. This is a gravel ridge formed by sediments deposited in a glacial meltwater channel flowing under the historic glacier.
  • Several glacial kames. Kames are landscape-scale sediment mounds that accumulated in depressions on a retreating glacier. They were then deposited on the land surface with further melting of the glacier.
