When Rebekah Lee was in her twenties, she decided to embark on an ambitious climb up Mount Stuart in Washington State and "made a series of bad decisions".
She and her two friends had arrived at the base of the climb hours behind schedule and with low water supplies, and spoke about whether to turn back - but decided to go ahead with the route anyway.
"We were young and dumb and had summit fever and really wanted to do that route and we continued anyways," Rebekah, a nurse, says. They ended up running out of water and finishing the climb 24 hours later than expected - but they were lucky.
"It could have been much worse than just being very tired and very dehydrated," admits the 34-year-old.
Climbers and mountaineers have always had to make difficult decisions during expeditions about how to stay safe, which routes to take and whether to turn back. They might not know whether they'll get exhausted, if the weather will get worse, or how big the risk of a serious accident is.
