Two hikers witnessed a rare occurrence while climbing a mountain in Mount Rainier National Park: their own optical illusion.
Radka Chapin and her husband Chris were standing on the summit ridge of
Washington's Tamanos Mountain on Saturday when they got to see an effect
known as a “Brocken Spectre.”
A "Brocken Spectre" occurs when a person is standing above the horizon,
causing a shadow to be cast on the mist or cloud below. As a result, a
circular rainbow halo forms around the shadow or "Spectre."
