Schoolhouse, Windowsill. A window, beneath the large boulder in the notch just west of the Schoolhouse, was reached directly from the north by Robert Fenichel, Mary L. Denman, and Robert Hoguet, III, on August 12. The route used was the face just right of the gully which leads from the slopes above Lake of the Crags to the window. This window is not visible from the vicinity of the lake, but can be discerned from the summit of Mount St. John. Of the four leads required to ascend this face only the first contained solid rock.
