The photographs in this section of our web site were taken in early October 2010 when my husband Pat and I accompanied the Sun City Lincoln Hills Gem & Mineral Society (Ron Clawson, Field Trip Leader) on a docent-led tour of the Penryn Quarry and Museum. For more information about the historical Griffith Penryn granite quarries, visit the “Placer County – Penryn” of our web site and the “Griffith Quarry Park and Museum” web site. Peggy B. Perazzo
