Linda and I went for an early morning hike on the Calavera Preserve this morning. It has a nice small lake and and a small mountain to hike up. The mountain is actually a volcanic plug where the molten lava came just to the surface and cooled into granite. Then over the years the surrouding softer sandstone has eroded away creating the mountain at a little over 500 feet above sea level just about 4 or 5 miles from the beach. From the top of the mountain on a clear day you can see up to about a hundred miles away to the Cuyamaca Mountains, Palomar Mountan, San Gorgonio Peak, San Jacinto Mountains and out to the Pacific Ocean.
