Black-tailed rattlesnakes are a rather fascinating species! They are absurdly versatile, occupying elevations ranging from sea level to nearly 8000′! I have encountered them in dry desert canyons, forests, along streams, and nestled among large boulders on rocky hillsides. Their captivating coloration and temperament are just as variable!
