The midnight hour I spent alone on the highest summit, one of the most impressive hours of my life. The deepest silence seemed to press down on all the vast, immeasurable, virgin landscape. The sun near the horizon reddened the edges of belted cloud bars near the base of the sky, and the jagged ice bowlders crowded together over the frozen ocean stretching indefinitely northward, while more than a hundred miles of that mysterious Wrangell Land was seen blue in the northwest - a wavering line of hill and dale over the white and blue ice prairie and pale gray mountains beyond, well calculated to fix the eye of a mountaineer; but it was to the far north that I ever found myself turning, where the ice met the sky. I would fain have watched here all the strange night, but was compelled to remember the charge given me by the captain, to make haste and return to the ship as soon as I should find it possible, as there was ten miles of shifting, drifting ice between us and the open sea.
