Our work in Ohio has focused on three locations, in addition to the many historic sites we have helped date: Brown’s Lake Bog, Wooster Memorial Park (also known as Spangler Park), and Odell Lake.

Brown’s Lake Bog

Research has been conducted at Brown’s Lake Bog, a Nature Conservancy preserve near Shreve, Ohio. Projects have been conducted in 2017 and 2011 with Dr. Wiles’ Climate Change class and in 2005 as part of an Independent Study project. In 2017, the class studied oak and maple cores to observe the recruitment of maples in the bog. We discovered that maples tended to be younger than oaks, therefore favoring the recruitment of maples over time.

In 2017 and 2011, cores of the bog itself were taken to investigate the bog’s representation of climate change events over the last 18,000 years. In 2017, Dr. Tom Lowell and students from the University of Cincinnati assisted Dr. Wiles in taking the core. At Wooster, the Climate Change class then gathered a variety of data — including the core’s stratigraphy, magnetic susceptibility, percent water content (used as a proxy of LOI), organic material viewed in smear slides, and color changes. Three samples were radiocarbon-dated to abrupt climate change events after the Last Glacial Maximum. Read more about the 2017 project here.

In the 2005 project, Brian Lutz ’05 investigated evidence of the 8.2 ky BP climate change event in the bog. Read the abstract of the resulting paper published in Quarternary Research, v. 67.

In addition to class trips in classes like Geomorphology, we helped Friends of Wooster Memorial Park study ash trees in the park in the summer of 2016 — counting dead trees, measuring tree girth, and coring a variety of living and dead trees.

Odell Lake

Taking a core from Odell Lake

Odell Lake was cored in 2006 to discover a peat layer at around four meters of depth. Dr. Tom Lowell assisted in the coring.
