Jason, I have a friend who lives near there. He's been on the mtn. several times and never seen a pyro. It's one of the places I plan to spend time at eventually, but the Santa Ritas are closer and the majority of my time is spent there. I have yet to visit Mt. Graham.
I'm curious as to where you were at on the mtn? As far as I know there's only one main road that goes up the mtn. Were you near the bottom when you spotted the pyro, or were you partway up? I'm curious because I want to know how they utilize the habitat, whether or not they come all the way down the mtn? In the Chiricahuas we've seen pyros all the way down the road in Portal, near the country store. But I guess that's still some elevation there.
The climate and habitat in AZ can be unforgiving. I learned my lesson the first time I climbed Mt. Wrightson, and that is mostly forest and much cooler. I didn't take any water and it almost killed me. I came down over four hrs. later, dehydrated, feet blistered, and spent the next days recovering. I never go anywhere w/o water anymore and drink frequently. Also, I never hike w/o proper footwear anymore. Trying to climb a mtn. in tennis shoes is asking for big trouble. I was made aware of how different it is in the West from more Eastern states that year. Since then I've taken it as a personal challenge to learn how to survive on a mtn and look forward to my first overnighter someday, only I won't take it lightly.
Thanks...TC
