Today, we"re celebrating the 102nd anniversary of southwest Utah"s Zion National Park with a visit to its Subway slot canyon. Zion is defined by its breathtakingly steep red cliffs, its maze of sandstone canyons, and its waterfalls with colorful hanging gardens. Visitors here can trek for miles, ducking into crevices and resting in canyons once occupied by the Ancestral Puebloans.
