I once visited the Joshua Tree National Park where I went off trail to visit the Heart Rock. It was a very short distance off trail so I wasn't very careful. Having found the rock easily (just a short distance off trail, maybe five minutes of walking) I relaxed and took a break near the rock. And by it was time to go back I had forgotten how I walked from the trail. It took me at least fifteen minutes to find the trail again.
Mistakes happen.
