Backpacking Guide, owner/partner of Backcountry Found (bcfound.com), for over 12 years. I've guided over 175 backpacking trips in the Grand Canyon and have taken thousands of photos of the big ditch in all its many moods and seasons. I used to shoot with a Nikon D90 until it reached the end of its very impressive lifespan (considering the banging, moisture, and grit it endured as my trusty camera for many years). Since then, I just shoot with my iPhone. I'm loyal to Nikon but am eying Sony alphas if I decide to invest in another DSLR. I hope you enjoy my pics of the canyon and my other global wanderings. :-)
