Set foot in the remote wilderness of Alaska, America’s last frontier – the perfect setting to learn about wildlife and ecology, and the balance between humans and natural resources.
Join Delaware Nature Society on this overland journey that immerses you in the stunning scenery of the Kenai Peninsula and Prince William Sound and enlightens the relationship between man and land, from early native communities to pioneering settlers and today’s modern inhabitants. As you kayak, canoe, and hike through magnificent landscapes amid forests and glaciers, observe sea otters and kittiwakes, search for moose, bears, and eagles, learn about salmon farming and commercial fishing, and discuss past and future effects of tectonic and climate events.
