History of Westchester County, New York, Vol. I
From its summit looking west the eye ranges over the whole twenty miles in length of the Manor of Cortlandt, the view being only terminated by the Rockland Mountains across the Hudson. The depression in which the latter lies is distinctly seen. Immediately in front of the spectator spreads the rich and affluent valley of the Titicus, the "Mughtiticoos" of the Indians, the eastern branch of the Croton, bounded on each side by high, irregular forest clad hills, the silver stream winding and gleaming through green smiling meadows till it falls into the Croton itself five miles away. Beyond it are seen the rich, rolling, fertile lands of Soniers and Yorktown, the foot hills of the Highlands their northern boundary. And further still the fair heights of the eastern bank of the Hudson and above them the lofty High Tor upon its western side. No more splendid scene can be looked upon in America, than to witness from this Mount the setting of the sun on a clear summer evening. The whole twenty miles of the Manor, hill, valley, river, and forest, glowing in the most brilliant radiance beneath the deep red tints of a gorgeous sky, and then as the great luminary, tinting their peaks with gold, sinks behind the blue Rockland Mountains, the whole suddenly blotted out in a deep purplish sombre gloom.
Upon the lower slopes of the height stands the old home of the Keelers, now the residence of Hobart Keeler, the fourth or fifth in a direct line who for a century and a half have always dwelt there. And yet it is so high, that from his dining room windows on a clear day. High Tor and the other Rockland mountains are plainly visible.
