The Narrows

By Eric Winkler

The Yellowstone River thunders through the narrowest part of the Grand Canyon of the Yellowstone at Calcite Springs. Yellowstone National Park, Wyoming.⁠ Water, calcium and sulfur from the volcanic fracture zone stains the canyon wall as the river slices towards the North entrance to the park at Gardiner, Montana.⁠ ⁠ On a moody, damp day like this, the river takes on a deep emerald hue, and steam rising through hydrothermal becomes visible (seen in the middle left of the frame if one looks closely).⁠
