Tower Mountain & Golden Horn

Tower Mountain shares a ridge with nearby Golden Horn. As evident from its name the peak's rock has a striking golden color as well as beautiful golden larches during the fall. This mountain offers great views of the Pasayten Wilderness, the Washington Pass area and the Glacier Peak Wilderness.

Tower Mountain and Golden Horn may be climbed in either order.  Just be sure to stay high in the Snowy Lakes basin when traveling from one to the other.

Tower Mountain (8,444 ft)

Ascend to the notch in the west ridge of Tower Mountain. Scramble towards the west face until a traverse leads to a narrow gully marked by a gendarme on its left. Scramble this gully to a notch in the ridge and then follow a ramp system in a broad gully. When the gully narrows, climb a smooth slab and then onto a ledge that leads to the ridge. Climb over blocks and a short chimney to a corner and then more block to the summit.

Golden Horn (8,366 ft)

Hike to Snowy Lakes at 6,700 ft and continue roughly northwest towards Golden Horn. Ascend a gully and talus to near the summit.  Class 3 scrambling leads to the summit.
