I had to question my judgement a couple of weeks ago, when at age 72 I descended several hundred feet into a canyon known as Cardiac. My Navajo guide tried to put me at ease, telling me their record was an 87 Year old. I'm not sure that helped, but the reality was, I wasn't that worried. After all, I've been pretty healthy and this was not my first gig running around the countryside with a pack full of camera gear on my back. It wasn't long before me, a friend, and one other guy hailing from Texas, were voicing our awe at what we were seeing in the narrow canyon surrounding us. The best was still yet to come. Once on the bottom we began our hike through the winding walls, sometimes narrowing to a body width. I had mounted my camera on a small travel camera, ready to stop and photograph compositions as they appeared. I had a plan. I would take three photographs, bracketed several stops apart at each location. The idea was to combine them into High Dynamic Range images during post production. My Camera was a Canon R5 with a Canon RF 15-35mm lens on the front. Every shot was taken at 15mm due to the nature of the canyon. After 5 and a half hours of exploring, we ascended out of the canyon (the cardiac part) and made our way  to a waiting van for the drive back to my parked truck. Fortunately the weather had been cool. A storm the night before had actually laid a beautiful coat of snow over the desert creating a beautiful scenic experience before we even entered the canyon. The snow was long gone by the time we were finished. My buddy and I loaded our gear into the truck, stopped at a restaurant for an early dinner, then started the long trip home. I was  pretty stiff for the next two days. I might have told my wife I needed to start acting my age. Then again, why would I do that?
