When people hear the disyllabic sounds, “alta” and “dena,” I would wager that most of them think of the well-known City of Industry-based Alta Dena Dairy, which was started by the three, Missouri-born Stueve Brothers in Monrovia, California in 1945. Oddly, more than five minutes of internet research haven’t helped me figure out why they named their dairy after a fellow San Gabriel Mountains community located some miles west of their hometown. Nonetheless, I based my map's "typeface" on their logo.
For a community that's never bothered incorporating, Altadena seems to have a very strong sense of pride, place and community. The first time I think I visited Altadena involved walking there from my workplace in Pasadena. Although my journey involved little more than crossing a freeway, once I arrived I felt as if, proverbially speaking, I was no longer in Kansas.
