Most of the low lying trails around Juneau involve hiking out and back. We are surrounded by saltwater on one side and the Juneau Icefield on the other, with glacier carved valleys hemmed in by high mountain ridges stacked up and down the coast. I remember my first year in Juneau, when I learned the geography of the ridges and valleys along the road system: Hawthorne Peaks-Sheep Creek-Mt. Roberts-Perseverance-Mt. Juneau-Salmon Creek-Blackerby Ridge-Lemon Creek-Heintzleman Ridge/Thunder Mt.-Mendenhall Valley-McGinnis. Up, down, up, down, up, down, up.
