San Diego has a somewhat unique distinction compared to other California cities. You cannot travel north from San Diego, by freeway, without going underneath an arch bridge. I-5 has one at Gilman Dr, I-805 at Eastgate Mall. I-15 has the one pictured near Pala with West Lilac Road crossing over. Now I-8 needs one, somewhere to make it complete.
On July 6, 2021 at 6 pm, I will be giving a presentation for the Historic Highway 99 Association of California on the history of US 99 through the San Gorgonio Pass. The route will be covered from Thousand Palms to Calimesa. Photos of the route, new and old, as well as maps showing the various alignments will be shown. Come join us!

Caltrans District 9 – Covering Mono and Inyo Counties as well as a portion of Kern County, has come out with a new bicycling map which details many of the routes in the region and alternates to roads closed to bicycling. The region is a great place to ride when the weather is conducive. Just beware of high winds and high heat at times.

There is a very cool phone app I have been using for a while. It is called “Rockd” and has access to geological maps and information throughout the US. In addition to the maps, it also has references to the sources, which is very helpful for geologists. Think of it as a geological map for anywhere you go. There are social aspects to the app as well, which can be fun, but I still find the maps and data to be the best. It is available for both Android and Apple phones. It is also free, developed by the University of Wisconsin. Try it out!

This map of the Lake Elsinore area comes to us from San Diego County dating from November 1883. At the time, Elsinore was a part of San Diego County. In 1893, this area became a part of Riverside County.
