This is a perfect spot for a picture postcard view of the Grenadier Range: You can see Garfield Peak, Greystone Peak, Electric Peak with Arrow Peak, Vestal Peak and Trinity Peaks in the background (from right). The Grenadiers and Needles are the only places in the San Juans where the basement rock withstood the range's period of volcanism. The range was uplifted around 70 million years ago. During the San Juans' period of volcanic activity, nearly the entire surface was covered with layers of lava and ash flows, but the volcanic flows would only lap at the Grenadiers' feet.
