I found one of these guys a month ago and always meant to identify it. Very cool.

This was a tough ID because of the image. Try resting your hands on something while taking the picture to stabilize. If this is possible to do without disturbing the animal too much, try placing them on a background that is even and contrasts with their coloration. It also never hurts to take too many pictures. Maybe one will come out.

Does this size description sound about right:
"Adults are 3/4 - 2 inches long from snout to vent (1.9 - 5.1 cm)."

The mask, coloration, behavior, and location leads me to think you have a Sierran Treefrog.

Thanks for the clarification Lisa! I never knew. These are the kinds of things I just haven't learned in school.

That is true. Rana is name more commonly used in older literature, but it isn't uncommon to still be seen as the scientific name for the species.
Amphibiaweb recommends naming frogs that are now treated as Lithobates by adding it after Rana. For example Rana (Lithobates) clamitans should hopefully clarify the species for viewers that are used to one name over the other.

The legs appear too short to be a cricket frog, so this is likely a juvenile of another species. I was not able to identify it here:

Maybe someone with more knowledge of froglets that morph around this time in the area would be more helpful.
