Here's a view of the Mount Washington's Jacob's Ladder Trestle looking West at 4,725 MSL. From this angle, the S-curve shape of the trestle is not terribly apparent, but the steepness and the height above the valley floor are obvious. While most of the trestle on this railway is of wood construction, Jacob's Ladder is a steel structure anchored in bedrock....undoubtedly because it is so exposed. The small building you see on the right side of the photo is called Halfway House....because it represents the halfway point in the trip to the summit. Halfway House is about 250 vertical feet below Jacob's Ladder. Although there is a steep, rocky trail that parallels the tracks up to this point, that trail ends right where the photographer is standing. Just out of view on the right, the terrain drops off very steeply, about 1,300 vertical feet into Burt's Ravine.
