The woman was visiting Grand Canyon National Park with two friends when, on Friday afternoon, she posted the pic (above) to her Instagram account, showing her sitting on the edge of Ooh Aah Point along the Canyon's South Kaibab Trail.
She captioned the photo:
"That view tho."
Just a few short hours later, she was dead. Park rangers found her body after she slipped and fell more than 400 feet.
According to her friend Jessica Roman, Colleen lost her balance while trying to move out of the path of another hiker:
"She was just, like, stepping out of the way for another gentleman to, kind of, squeeze in. Unfortunately, Colleen just kind of got tripped up on her own feet and fell backwards. She fell into the canyon. That was the longest, strangest, craziest two seconds of my life. Those last two seconds where everyone changed are so minute in comparison to all the memories I have with her."
We honestly can't even imagine what it'd be like to go through a situation like this, to see your friend fall helplessly before you…
A park spokesperson with the Coconino County Public Health Serviceconfirmed Burns' death came from "multiple blunt force injuries," and indicated officials are still looking into it, having to this point ruled the tragedy an accident.
Such a sudden, sad way to go on what otherwise would have been such a fun day for three tourists visiting an incredible national park.
Our thoughts are with Colleen's friends, family, and loved ones.
The YouTube celebrity posted a lengthy, emotional video revealing that she and her husband are ending their marriage.
While sharing the sad news with her over 4 million subscribers, Colleen immediately broke down, saying:
"I am dreading making this video. I'm just going to say it. Joshua and I are getting a divorce. Man, that sucks to say out loud."
But, Miz Ballinger stressed that her former flame didn't wrong her in any way, adding:
"I want to start off by saying Joshua is a wonderful man, and I am so in love with him. This has nothing to do with he's a bad person, or he did something horrible to me, or anything like that. He's a good person and I love him."
Instead, the singer clarified that they ultimately weren't a good fit together:
