I'd just finished reading Wynne Brown's biography of Sara Plummer Lemmon called "The Forgotten Botanist" and was reminded that Sara and her husband JG Lemmon spent a lot of time botanizing the Huachucas, an Arizona Sky Island I'd never visited before! I looked on a map and quickly started planning my trip there.
Torrey pine trees are a rare pine species only found in this area near San Diego and on Santa Rosa Island, 175 miles away off the coast of Santa Barbara. There's been a concerted effort to keep them protected since they are so rare.
