Water, Water Everywhere—But You Can Still Get Heat Exhaustion
Pro tip: Don't underestimate the desert sun
Like every desert river, Utah's San Juan is a deceiver. Beyond the river's banks, the terrain is arid, harsh, and potentially deadly. I forgot that during a spring trip with two friends and a dog. We had a raft, a kayak, and some exquisite geology all to ourselves.
Pam, Dave, and I wanted to hike to the Mule Ear Diatreme, a cool volcanic plug we thought was not far from the river. We started up out of the canyon in shorts, sandals, and river-soaked shirts.
It was glaringly bright. My water was running low, but I rationed it and said nothing, assuming the Diatreme must be close.
I didn't know I was in trouble until I slowed and became nauseated and dizzy. My conversation with Pam flagged. She asked if I was OK. Assessing that I was in trouble, she started barking like a drill sergeant.
Pam marched me to some shade and made me drink my water. Had my inner temperature kept climbing, I could have died. Now I hike in long, light pants to avoid evaporation and keep the sun off—and I'm not so stubborn.

"Heat-related injuries can develop suddenly, especially in the desert. Immediate rest, shade, and hydration were the right responses here. But prevention is key: Drink lots of fluids, cover up with light, loose clothing and a sun hat, know your terrain, know your abilities, and pace yourself."
