Contour map of Perch lake and vicinity, showing- numerous low 

 terraces in the thin soil. In many parts these terraced rocks are 

 nearly or quite bare. On the southeastern shore of the lake the 

 slope is quite abrupt. On the west shore the extensive swamps, 

 separating the cliffs from the lake, probably always hindered much 

 occupation, but the proximity of the river to Linnell's island made 

 that a desirable residence.
