Maybe You're Not a Spadefoot

When I took the picture of the little guy that I used in my title block, I assumed he was a spadefoot toad because it was monsoon season and he sort of looked like one. I didn't pick him up to see if he had the infamous "spade" on the back of his foot because I didn't want to bother him. But now...I have become curious. What is he??? Actually, his feet look like frogs feet. I have searched all over the net, on the Sonoran Desert Museum website, and a few other herp sites, and it's still not clear. He actually looks like a barking frog, but supposedly their range is not in Gisela, where I found him. I'm confused!
