We celebrate National Park Service Founders Day today with this photo from the John Muir Trail near Mammoth Lakes in California. The 210-mile trail is so long, to hike it all would take you through three national parks: Yosemite, Kings Canyon, and Sequoia. At 102 years old, the National Park Service continues to do the day-to-day work of preserving our parks ‘for the enjoyment, education, and inspiration of this and future generations.’
