Botsford Nature Preserve—Yates County


The Botsford Nature Preserve, north of Keuka Lake, offers a window into the fascinating geologic history of the Finger Lakes. Join geologist George Thomas on this walk to interpret the preserve’s relatively recent glacial history as well as where Big Gully Creek has cut into the underlying bedrock to provide a view of the 375 million-year-old past. The geologic evidence from the Botsford Preserve will also be used to discuss the geologic development of the Finger Lakes region.

As part of our trek, we will walk down into the gully and along the beautiful creek where footing is extremely uneven on wet and slippery rocks. Please wear appropriate clothing and footwear that you don’t mind getting wet.


From Branchport, take Route 29 north/Guayanoga Road for two miles. At the intersection with Hemlock Road, make a left turn to find the parking area on your left.


Except in the case of extreme weather, walks go rain or shine. Please check this web page for updates.

Please refrain from bringing dogs as they may impede the observation of wildlife.
