Which detail in the text helps unfold the idea that the United States' national parks belong to all Americans?
(12) Mount McKinley stands more than 20,000 feet above sea level, and 17,000 feet above the surrounding valleys.
Scenically, it is the world's loftiest mountain, for the monsters of the Andes and the Himalayas which surpass it in
altitude can be viewed closely only from valleys from five to ten thousand feet higher than McKinley's northern
valleys.
(13) The Hawaii National Park contains the fourth greatest dead crater in the world, the hugest living volcano, and
the Kilauea Lake of Fire, which is unique and draws visitors from the world's four quarters.
(14) These are the principal features of America's world supremacy.... No wonder, then, that the American public
is overjoyed with its recently realized treasure, and that the Government looks confidently to the rapid
