Kudos to the Arizona [Tucson] Daily Star and science reporter Tom Beal for their Centennial salute to science in Arizona. Each day, for 100 days, they are reporting on "a milestone in the state's scientific history."
Two recent stories look at geologic topics - "Mining has been state's bedrock industry"
and today's feature on "Tree-ring study became a science here."
