The Peter’s Kill and Lake Minnewaska

Arlington High School Field Trip Data

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.
