America The Beautiful: Wild South West ...

 
The most beautiful secret in Texas hides along the border, where the Rio Grande meets mountains: Big Bend. Black bears raise their young in the airy Chisos Basin, above summer's heat. The first thunderstorm awakens an army of spadefoot toads that burst from underground hiding places. Night falls with howls from the fearsome grasshopper mouse. This desert Eden has long thrived – concealed until now.
