Sabino Canyon's 'gneiss' rocks


There's a multi-page article and photo-tour of the rocks of Sabino Canyon in Sunday's Arizona (Tucson) Daily Star. AZGS's Mike Conway was consulted on the geologic history and road log, in the story ("Sabino's a gneiss canyon") by reporter Doug Kreutz with photos by Dean Knuth. [right, my photo, 2006]
