Things can go wrong, fast.
A series of decisions, all which seemed reasonable at the time. Even experienced hikers can get lost in canyon country.
Three friends, planning on a challenging day hike on the standard Syncline Loop in Canyonlands National Park, Utah, got stuck overnight without provisions. One suffered some hypothermia.
Rich posted a detailed account of how it happened:
Now, we didn’t really have much in the way of food. I had brought a few slices of bread, some saltines, a jar of peanut butter and, of course, plenty of water. We each had a similiar supply.
We planned on stopping at the grocery store on our way to Moab but, somehow that slipped our minds. …
So, we figure … we’d probably find a bit of trail food at the visitor center.
Well, we soon found out there was nothing at all in the way of trail food at the visitor center. The Island of the Sky Visitor Center is a little more than a Ranger Station. In fact, I really like Canyonlands because it doesnt have any amenities.
The desert is one place your really do need the 10 essentials. And extra water. Even if setting out only for an hour or two.
They made one last urgent scramble to get up and out.
… we saw … a potential exit. It was crazy and we were all really uncertain but, we pushed on. Every second getting closer to darkness.
Of course, as they do in the desert, temperatures plunged with the setting sun. Thankfully, we still had clear skies and little to no wind. We climbed higher and higher.
… It is endless!!!
For certain, that mile or so was the most intense and rugged hiking I have ever done in my life. Naturally, I loved every minute of it but, my lungs would argue otherwise. We had been on the trail for nearly 10 hours.
No pretty pictures on this post. Just three wiser hikers the following morning when the sun finally came up. Cold, but never in any real danger.
