The Peter’s Kill Site
The Peter’s Kill is a stream that flows out of Lake Awosting.
We are sampling at the gate house to Lake Minnewaska.
We sampled on both sides of the bridge.

The Sunset Carraige trail
Observations up to the LakeWe observed evidence of the Wooly Adelgid and
elongate hemlock scale on Hemlocks and many dead Hemlock trees.
We identified trees, fern and moss life cycle stages and observed primary and secondary succession.
