Sightsee by jet boat or rubber raft on the McKinley Queen. See Mount Foraker, Mount Hunter, and Mount McKinley from the confluence of the Talkeetna and Susitna Rivers at Talkeetna, Alaska, USA. Denali (20,310 feet or 6191 meters, aka Mount McKinley) is the highest mountain peak in North America, and measured from base to peak, it is earth's tallest mountain on land. Mount McKinley is a granitic pluton uplifted by tectonic pressure while erosion has simultaneously stripped away the somewhat softer sedimentary rock above and around it.
