Bay Area Geology: Episode 19

Audible Mount Diablo is an invitation to adventure. Its free multimedia tours combine lively interviews and music with the rush of wind and the chirps, howls, and growls of wildlife. Naturalists heighten visitors’ appreciation of the sights and sounds at each stop, tell tales of the mountain’s past, and suggest what to look for around the next bend.  Perfect to prepare for your first--or your hundredth--trip up the mountain.
