Garrisonville
In the region about the ravine, Mrs. Ann Garrison, in pioneer times, laid out a paper city, much to the regret of lot purchasers in Philadelphia and elsewhere. The sawmill, the pottery, the hotel, and the "salted" gold mine are but memories now.
The gap where the river escapes from the valley into the lowland to the north, has a geological history similar to that of Devil's Lake. No talus covers the slopes, however, the loose stones having been swept away when the ice sheet flowed slowly through in glacial times.
