EXPLANATION OF PLATE 7

Upper figure shows gully in southeastern part of Reservation, which

has enlarged and deepened greatly in the past 40 years. Heavy

precipitation in the summer of 1951 resulted in the undermining and

collapse of many large and medium sized trees, as shown in this

photograph taken in March, 1956, by H. S. Fitch.

Lower figure shows Cottonwood fifteen feet in circumference,

growing on hilltop near south edge of the Reservation. This is the

largest tree on the area. Several exceptionally large black oaks,

chestnut oaks, and elms are present on the same hilltop. Photograph

taken in December, 1954, by H. S. Fitch.]
