NEW MEXICO ABOUNDS in geologic wonders, from Ship Rock to Carlsbad Caverns, Capulín Volcano to Rockhound State Park, and a zillion dunes, plains, mountains, and gorges in between. Wouldn’t it be nice to have a geologist riding shotgun to explain it all? New Mexico Rocks!, by Nathalie Brandes (Mountain Press Publishing), earns a window seat with its concise descriptions of what the eons have wrought on our landscape. Arranged by region, her overview includes maps and graphics, plus photos by her husband (and fellow geologist), Paul Brandes. It’s already inspired my next road trip. Blackwater Draw, here I come.
