Up and down winds the way until a point is reached where the ancient river valley turned to the eastward. Half way down the precipice, you can make it if you are an expert mountaineer, is Balanced Rock, a huge piece of elongated quartzite, shaped much like an inverted dash churn of log cabin days, big at the top and little at the bottom. From the location of Balanced Rock or from the top of the bluff above may be obtained a rare view of the valley. Devil's Doorway To the east a few hundred paces is the Devil's Doorway, a quaint arrangement of rocks left as the result of the washing away of the stones and earth through long periods of rain and frost. Once a Waterfall Just east of the Doorway the careful observer will find a number of potholes, rounded places in the hard quartzite. These were undoubtedly once in the bed of a river, where a waterfall was an interesting object on the landscape. Potholes can be made in no way except by running or falling water. Unless the visitor desires to explore the bluffs to the east, the descent is now made a few rods from the potholes. At the upper end of the trail will be noticed a quantity of preglacial gravel about which Professor R. D. Salisbury and William C. Alden and others have written. Reaching the trees below and keeping close to the rocks, Alaska Grotto will be reached a few rods to the west. If a warm day, go into the depression and feel the flood of cold air pouring outward. Crossing the railroad track to the shore of the lake, the large bird effigy mound will be noted near the hotel. The length of the body is about 115 feet and the wingspread about 240 feet. There is a bronze tablet on the mound. The West Bluff On the West Bluff may be seen Cleopatra's Needle, the Turk's Head, and other points of interest. This bluff is often called Palisade Park, so named by A. R. Ziemer who platted a summer city and exploited the place in 1894 and 1895. The young man died in his cottage in the early winter of 1895 and soon the project fell into decay. The observation tower, his home, the Marsh & Jackson Cottage, and the Coleman place became ruins. Spring Koshawagos Spring, some distance from the southwest corner of the lake, supplies the finest water in the whole locality. It takes its name from the Koshawagos Club House hard by, the word meaning "Men of the Valley." The Indian Mounds Besides the animal effigy on the north terminal moraine and the bird near the Kirkland Hotel, the following may be mentioned: a low mound west of the Cliff House site cut by the railroad: two linears about thirty rods to the west, one extending into the public road; and the Terminal Moraine group in front of the Claude Cottage. A bear effigy, a linear and still another effigy are quite plainly outlined while two others are almost obliterated.
