10 national park record-setters: Highest, hottest, longest, deepest
( CNN) Yellowstone, Yosemite and the whole country of Switzerland would fit inside the United States’ largest national park, a 13.2 million-acre space in Alaska.
And it would take about 2,400 of the smallest of the 59 headliner national parks to crowd the biggest park’s pristine, rocky terrain.
Elsewhere in Alaska, climbing North America’s tallest crest takes trained mountaineers two to four weeks, round trip, while visitors to the world’s hottest recognise — which is also North America’s lowest and driest blot — are advised to “travel prepared to survive.”
The world’s longest contiguous cave organization isn’t yet altogether searched, and it may never be.
All these ponders are protected within 413 national park areas spanning more than 84 million acres, all overseen by the US National Park Service in every position, the District of Columbia, American Samoa, Guam, Puerto Rico and the Virgin Islands.
