Here is the mandatory photo of the group at the top of Sandstone Peak. And why is this so important, you might ask? Because Sandstone Peak is the highest mountain in the Santa Monica Mountains (3,111 feet above sea level). For the rest of the day we would be descending those 3,111 feet to reach our ultimate destination of Point Mugu at sea level. Of further note are the facts that (1) the plaque at the top says that the peak is really Mount Allen and (2) it is made of andesite breccia, not sandstone.
