I hadn't studied up on my Texas herps very carefully when I visited Hill Country State Natural Area, so I was surprised to discover a brightly-colored small frog quite a long distance from any rivers, creeks, or ponds.

After having gone a lifetime unaware of the existence of this interesting little frog, I found another the next day. This one was larger (though still little), but not quite as brightly colored.

Apparently there is at least one of these frogs in every parcel of public land in the Hill Country region of Texas.
