National parks across the country are preparing for the arrival on Sunday of sky-watchers and photographers anxious to take in an annular solar eclipse amid the natural beauty of wide open spaces, and Grand Teton National Park is no exception. The Grand Teton eclipse is expected to occur as the sun sets above the Teton Range, and it should offer a dramatic show of natural splendor for greater Yellowstone area photographers and astronomers.

The National Park Service will host a Grand Teton eclipse viewing event starting at 6 p.m. Sunday, May 20, at the Willow Flats Overlook, north of Jackson Lake Junction. Bob Hoyle, a professional astronomer and park ranger naturalist, will conduct the event in partnership with the Jackson Hole Astronomy Club.
