This plate previously reproduced as a plate photogravure in the October, 1892 issue of Sun & Shade.  The following observations by Stoddard appear in the index:

Of the picture Mr. Stoddard writes: This lake is in the Adirondacks four miles south of the head of Keene Valley and a little east of the centre of the main cluster of the Adirondack Mountains. It is about 1,900 feet above tide water, a little over a mile in length, and an eighth in width. It is noted for its beauty and the wild nature of its surroundings, being with one exception, perhaps, the wildest of all Adirondack Lakes. Its shores are almost impassable, descending abruptly to the water’s edge, in places vertically for a good many feet. It is reached over a road kept in good condition by its owners, the “Adirondack Mountain Reserve Association,” who charge toll to defray expense of its maintenance. At its outlet is a rustic cottage and boat house which is the only habitable structure on the lake. Boats can be secured here by visitors coming with duly authorized guides from Keene Valley, and the right to pass through this lake to the Upper lake, where there are several rustic camps, furnishing wild-woods accommodations of blazing camp-fire and bed of cedar boughs.
The place is reached usually by rail to Westport, and by stage the rest of the way via Elizabethtown and Keene Valley. The nearest hotel is “St. Hubert’s Inn,” an excellent house standing at the head of Keene Valley, four miles from the scene of the picture. 1.
