The U.S. Department of the Interior, which oversees America's public lands, is collecting photos from everyone who has visited any of the country's national parks or wildlife refugees this this summer and is posting all those great pictures into a Flickr photo collection called "Summer in America's Great Outdoors." It's also sharing some on Instagram.
Think of it like a virtual scrapbook of America's most amazing places to hike, bike, fish and camp.
We've pulled some of our favorites from the growing collection. You'll find a wedding amid towering sandstone arches in Utah's Arches National Park; kayaking in the same waters as the famed explorers at Lewis and Clark National Park in Oregon and Washington; witness Yellowstone's multi-colored hot springs bubbling to life.
America's national parks host about 280 million visitors each year, according to the National Park Service. Up to 10 million people a year visit the Great Smoky Mountains National Park, located in Tennessee and North Carolina, making it the most visited national park in the country.
