With TheJacumba Hikers
Round Mountain in Jacumba, is an extinct Early Miocene Volcano, it can just south of Hwy 8 near the Jacumba Turn off. In the vicinity as one drives by it can be noticed ash layers and the bright colors from the Volcanic past. Nearby Jacumba Hot Springs is another hint of a volcanic past. The photo below shows Round Mountain from The Jacumba Turnoff, the southern side is the more gradual slope up.
The Summit of Round Mountain, The Jacumba Hikers have just replaced the flag and are settling down to eat lunch and soak up the ambience.
The video will pan a 360 degree, first you can see The de Anza Springs Resort and Temple Peak ,the Stone formation next to it, then past Jacumba.
