Description

This pair was found together, exactly as you see in the second and third photos. I love their cryptic pattern, and they way they act like stones. In this area there were both red and white stones.

Description

Injured on Road, blood around mouth, with dried tissue (tongue?) sticking out. Animal was BAR (bright, alert, responsive) however. Possibly hit by white F150 that had passed quite some miles back (only vehicle to pass me heading south after having turned onto US 385 south at Marathon; no vehicles passed me heading north).
