OUR HERITAGE

Dictionary Hill, originally known as Lookout Mountain, is a noted historical site. More than 150 years ago, Rufus King Porter, one of the founders of Spring Valley, climbed the mountain to see if the steamer had arrived before making the trip into Old Town to pick up mail and sell his produce. Today, from the top of Dictionary Hill, it is still possible to watch ships entering San Diego Bay.
