Inspired by a recent trip to Yellowstone National Park, this gallery contains some of the country's most spectacular national parks, as seen from space.
Yellowstone's geothermal features are strange enough from the ground, but from orbit they seem even more incongruous (above). The Landsat 7 image below shows Yellowstone Lake and the entire park in false color, which highlights certain features that might not stand out in true color. Water appears dark blue or black, and snow is light blue. Grass fields appear light green, the dark red-and-green is mature forest, and young forest, such as has grown back since the 1988 wildfires, is pink.
This collection of 21 national parks and one monument includes many of our favorites we've visited and a few we hope to add to the list someday.

Yellowstone was the first national park in the country, and in the world. Its famous geothermal features -- including the Grand Prismatic Spring (shown above), Old Faithful and more than 200 other geysers -- are fueled by a mantle hotspot. The park's other main attractions are its many large mammal species including grizzly bear, moose, gray wolf, lynx and bison. And of course, the excellent trout fishing.

Location: Florida
Established: May 30, 1934
Size: 2,357 square miles
Visitors in 2010: 915,538
The marshy, subtropical Everglades park has 36 threatened or protected species living in it, including the Florida panther, West Indian manatee and American crocodile. The park was created to protect the fragile wetlands that were vanishing as the area was drained for agricultural and residential purposes.

Crater Lake National Park
Location: Oregon
Established: May 22, 1902
Size: 249 square miles
Visitors in 2010: 448,319
Crater Lake was formed when a stratovolcano called Mount Mazama collapsed during a massive, explosive eruption 7,700 years ago that blew ash 30 miles high and deposited it over much of the Pacific Northwest and parts of southern Canada. The 1,943-foot deep lake is the deepest in the U.S. and took around 740 years to fill.

Denali National Park
Location: Alaska
Established: Feb. 26, 1917
Size: 9,492 square miles
Visitors in 2010: 378,855
Denali contains the highest mountain in North America at 20,320 feet in elevation. The peak is officially recognized by Alaska as Denali, but is known as Mount McKinley to the U.S. Board on Geographic Names. The first known ascent of Denali's main summit was in 1913. More than 1,000 climbers visit the mountain each year, but historically only a little over half of the summit attempts are successful. More than 100 people have died on Denali.
