This image is also from the Brockway Mountain Drive, now much further to the west, looking westward towards Bailey Lake, Upsom Lake and Agate Harbor. Upsom is the closer of the two lakes in the distance, Bailey the more distant, while Agate Harbor is the lake shore to their right.
The ribbon of cleared trees in the right middle is the continuation of Brockway Mountain Drive towards the west. The closer lake is now spelled Upson on modern maps.
The caption states:
