There are countless backcountry routes and possibilities in this wild land. The diversity of climate and geography creates very different habitats on the west and east side of the crest, as well as fostering a great array of plants and animals.
Cascading water is fed by over 300 glaciers and countless snowfields. Lakes are abundant. Almost 400 miles (644 km) of trails, mostly in major drainages and over high passes, traverse this tremendous landscape.
Your path may follow a route used for many centuries by people who have long crossed these mountains or sought food and resources here, or you may venture to an area so wild it feels as if you are the first explorer.
