On the sea, it is known as the exponential curve of non-recovery: A mistake leads to danger, which leads to another mistake, which leads to more danger, which leads to more mistakes until a boat reaches a non navigational point and sinks.

That principle can apply no matter where you are – on water or land – if you are in the wilderness; it did here.

A body was found Wednesday near the Black Bridge at the bottom of the Grand Canyon. The body is believed to be missing Texas doctor Sarah Beadle.

The bridge is just a half-mile form the Bright Angel Campground, where Beadle had a reservation to spend Tuesday night with her daughter and nephew.

The 38-year-old from Fort Worth, Texas was reported missing when she didn't show up for the reservation.

Her daughter Laura and nephew Evan, ages 10 and 11 respectively, were found safe and sound.

The three had set off Tuesday morning from Grand Canyon Village, indenting to hike the South Kaibab Trail down to the campground at the bottom of the canyon.
Dr. Beadle's husband Scott, says he was told that their daughter started feeling dizzy from heat exhaustion on the way down, after they ran out of water.

The Texas doctor and her two kids, ages 10 and 11, were scheduled to spend the night at the Blue Angel Campground at the bottom of the canyon. Her children were later found safe

His wife left the kids in a safe location to go get help, but appears to have gotten lost.

‘Somewhere along the trail, she made a wrong turn and got lost,' Scott said. ‘The park rangers suspect she died of heat exhaustion. Another hiker found [the children], gave them some water and escorted them to the camp. Search and rescue was notified …'

Temperatures on Tuesday hit a high of 86 degrees in the Grand Canyon.

The National Park Service warns hikers that water is not offered along the South Kaibab Trail.

‘Everyone needs to carry water! A common mistake is not carrying water or not carrying enough water,' park officials write in a flyer about the trail. ‘When hiking in a group, each person should be carrying water. Remember to eat as well as drink while hiking, you use a lot of energy hiking the canyon.'

When she first went missing, authorities said that Beadle was an experienced hiker and had previously hiked the Grand Canyon in 2002.

The point that should stick out to everyone is that Sarah Beadle was not a novice hiker and had hiked the Grand Canyon before as well as many other places.

She knew what she was doing; but in the wilderness, one mistake can lead to danger and another mistake and more danger until you are dead.
