Trona Pinnacles! At the Northwestern most edge of San Bernardino County is a strange geological structure. They are giant Tuffas or mineral build up from an ancient lake. The pinnacles are located on public lands and stand just a few miles from the small town of Trona. A mining town that produces borax, salt cake and other minerals used for industrial products. #travelgram #instatravel #adventure #explore #photooftheday #nature #vacation #traveling #instadaily #bartellsbackroads #abc10tv #pitsto
