Saw two lizards. One about 6-7” long, brown with a long tail. The tail had a different texture from the rest of the skin, divided quilt-like by low ridges. He had a funny habit of crouching low on his heels, so his back feet poked up. The other had a white belly, ornate patterned strips cross-wise on the tail and continuing onto the body. He stood alert on a rock and waved his tail warily.
