The first thing we shall notice as a natural attraction on the island, is what is called "The Arch Rock." This is a natural arch projecting from the precipice on the northeastern side of the island, about a mile from the fort, and elevated about one hundred and forty feet above the level of the water. Its abutments are formed of calcareous rock, and have been produced by the falling down of great masses of rock, leaving a chasm of eighty or ninety feet in height, and covered by the arch which spans it of fifty or sixty feet sweep. The scene presented by cliff and chasm is one of wild grandeur. Like the Natural Bridge of Virginia, it possesses an attraction to all fond of natural curiosities, sufficient of itself to justify a visit to the northern lakes. The view from the beach is particularly grand. Before you is a magnificent arch suspended in mid air. Indian tradition says that this wonderful arch was formed by the giant spirits who inhabited this island. Geological tradition, however, indicates that it was formed by the action of the waters, which were at a remote period much higher than at the present time. The next object which strikes the attention of the visitors is the "Sugar Loaf Rock," a high, isolated, conical rock which, resting upon the elevated plateau that forms the next highest point of the island from that of Fort Holmes, exhibits a rise of some sixty to eighty feet. This is but little less than the elevation of the ridge which forms the crowning plan of the island, and upon which the dismantled post of Fort Holmes is seen, being separated therefrom by a distance not exceeding one hundred and fifty yards. By what violent throe of nature it has become severed from the adjacent ridge, of which it no doubt, formed a part, is matter of curious inquiry. Has nature done this by gradual recession, or by the slow upheaval of the land? On inspection, this rock is found cavernous, slightly crystalline, with its strata distorted in every conceivable direction. In its crevices grow a few cedars and vines. As the visitor approaches it by the road side its effect is grand and imposing; still more so, perhaps, when beheld from the top of the ridge, where its isolated position with its bold form, breaking the outline of the island, strikes the beholder with wonder and admiration.
