The sound of rushing water increased in volume and the canyon walls pressed in close and reached toward the sliver of sky overhead as we walked downstream in the calf-deep North Fork of the Virgin River in The Narrows of Zion National Park. Turning a bend in the canyon, we came upon one of the most incongruous sights in the desert: a waterfall pouring from cracks in the canyon’s sandstone wall. Known as Big Spring, this oasis of cascading water and a hanging garden clinging to a redrock cliff is just one of the many wonders awaiting backpackers in Zion’s Narrows.
