Severe winds can cause damage even to these old veteran hemlocks. They exceed 200 years of age, and withstood storms until soil moisture, wind strength and direction, and their own large size led to their destruction. Prior to the storm, no cutting had occured here within 50 years. Some logs were salvaged.

Mature hemlock and yellow birch probably exceeding 200 years of age. An analysis of growth rings on nearby hemlock stumps indicates that severe windfall probably occured about 1790, and that cutting occurred about 1860 and 1905.

Some of the oldest and largest red spruce in this area. On a similar, nearby area, two hurricanes within an 8-year period destroyed 20 sq. feet of basal area of spruce. The eastern spruce beetle population probably built up in the windfall and they now are attacking and killing some large spruce like these.
