Rain date—Sunday, September 10, 2023


We will start at 9:30 AM at the Lindsay-Parsons Biodiversity Preserve in West Danby, then travel to the Thayer Preserve in Ithaca.

Both preserves are located in Tompkins County. See directions below.


Join geologist George Thomas on this trip to visit two iconic Finger Lakes Land Trust nature preserves—the Lindsay Parson Biodiversity Preserve (LPBP) and the Thayer Preserve—to view different aspects of the local geology. George will discuss the geologic origins and setting of each of these preserves and their relationship to the overall geologic development of the Finger Lakes region.

We will walk approximately one half-mile on maintained trails at the Lindsay-Parsons Preserve to the main overlook, then drive individually to the Thayer Preserve to view the gully. Please wear appropriate clothing and footwear for walking on wet and slippery rocks.


We will meet at the Lindsay-Parsons main parking lot and then travel individually to the Thayer Preserve. Overall time is expected to be about 2.5 hours including travel time between the two preserves.

The Lindsay-Parsons Biodiversity Preserve is located in West Danby, about 8 miles from Ithaca. Take Rt. 13 south from Ithaca, then follow Rt. 34/96 south to West Danby. Most of the preserve is located on the east side of the highway, across from Sylvan Drive and the West Danby Fire Station. Ample parking is available about 1/2 mile south of Sylvan Drive, on the east side of the road. The entrance to the parking lot is at the top of a hill. GPS: 42.30908002664574, -76.52214803035609

From the Lindsay-Parsons Preserve to the Thayer Preserve, head north on Rt. 34/96 toward Ithaca for just under six miles. Turn right on Blakeslee Hill Rd, and after one mile, turn left onto Townline Rd. After one mile, you will reach the Thayer Preserve. Parking is available on the left side of the road. (The Sweedler Preserve is to the right, and the Thayer Preserve is to the left.) GPS: 42.39575623417477, -76.5331106285041
