A Florida woman fell to her death on Friday from stumbling off a trail at Grand Canyon National Park.

Colleen Burns, 35, posted a picture of herself sitting on the edge of a cliff to Instagram shortly before accidentally stepping off an edge at Ooh Aah Point, the The Associated Press reported. Her body was found 400 feet from where she fell.

Jessica Roman, a friend who was taking photos of the sunrise with Burns when the accident occurred, told WESH that Burns “tripped up on her own feet and fell backwards” after stepping out of the way to let a man get a better view.

Burns’ death was announced on Monday and commemorated by friends and family on social media. The Orlando native worked as a regional marketing director for Yelp. The company remembered their late employee by tweeting a photo of Burns captioned, “There are no words. Hoping to find some soon.”

DJ Kaskade posted a photo on Facebook of himself with his late friend sharing his grief over the tragedy. “She had such an unmatched enthusiasm for life; the fire in her eyes and that crazy infectious smile,” he wrote. 

The National Park Service and the Coconino County Medical Examiner are reportedly investigating the incident.
