What a perfect day for rockhounding, up over 7,000 feet in the cool mountain air and warm southern California sunshine of Wrightwood. Our group assembled in the parking lot between Jensen's Market and the Cinnamon's Bakery. It seemed that everyone had a cinnamon roll a minute after arriving. Oh the tough life of a rockhound. 

Up we drove through the tall pines along the Angeles Crest Hwy past Inspiration point in search of a Serpentine deposit opened by a road cut. 

Easy pickens in this metamorphic rock region. Many varieties of associated Amphibole minerals are found in this one spot, from chrome Tremolite to black Nephrite. Rich, Karen and Darlene were up the side of the mountain in no time. The snow plow had left plenty of material across the street for even easier collecting. No one left empty handed, but we weren't done yet. 

Next stop was for Actinolite, a light silver-green, grayish at times to dark green, radiating crystal bladed mineral. The darker the green, the more iron. This location Northeast of town also never disappoints the keen-eyed rockhound. Karen found a beautiful grapefruit sized stone of Actinolite not more that twenty feet from her car. It's not how far you walk but how long you look where your standing. Once your eyes adjust to the dusty gray-green color of everything, it starts to jump out at you. The eleven of us had a wonderful time adding to our rock collections. Collecting mountain style in the cool pines was a nice change from our usual desert rockhounding.
