Upcoming Meetings

Saturday, May 18, 2019 - Hike to Indian Rock @ Tyler Arboretum

Time: 10 am
Location: Tyler Arboretum Details
Speaker: Don Nigroni
At Tyler Arboretum in Delaware County by the picturesque Rocky Run sits a peculiar artifact known, at least since 1907, as Indian Rock. Our guide, Don Nigroni, will relate the theories as to what Indian Rock might really be and we will discuss the local history of the Lenape and a strange document, the Walum Olum, ascribed to them. Robb Kerr will be providing botanical information about this scenic Piedmont site and Kim Sheridan will be photo-documenting the day's activities.
We will meet at the Visitor Center by the parking lot at 10:00 AM, then we will hike from the Visitor Center along the Blue Trail for one mile each way to inspect this mysterious stone. Although we may not figure out what Indian Rock really is, we will learn about the history and natural history of this Piedmont site.
Bring insect repellent, sturdy shoes, water, lunch, and a camera.
