Ridgecrest – Part 2 Now Online

Part 2 of my Ridgecrest earthquake field trip is now online. This time, I also won’t forget to add a link!

Ridgecrest – Part 1

Finally posting the photos from my August 22, 2019 Ridgecrest trip. Part 1, which covers the fault rupture, is finally up. Part 2, which will cover the problems in Poison Canyon and Trona, are coming soon!

The Grapevine?

Current Roadway Conditions and Detours

I-5 between Santa Clarita and the San Joaquin Valley is commonly referred to as “The Grapevine” by locals and traffic reporters. Most assume the name derives from the twisty nature of the original roadway – the Ridge Route. That road was indeed very twisty, much like a grapevine. However, that is still not the reason. The name Grapevine actually comes from Grapevine Canyon, where old US 99 and I-5 come down from the mountains and into the San Joaquin Valley. The canyon is called such as wild grapes grow along the canyon walls. It was formerly known as Canada De Las Uvas which is Spanish for Canyon of the Grapes. The name Tejon Pass is also a “new” addition to the area. The current Tejon Pass was known as Grapevine Pass or Badger Pass until the 1850’s. Old Tejon Pass, much farther to the east, was a very treacherous route. That pass was eventually abandoned in favor of the current Tejon Pass. The name was just shifted to the new route.

After the 1933 bypass of the original road to as late as the 1970’s, the roadway over the mountains was still referred to as “The Ridge Route”. It wasn’t until the 1980’s that the name “The Grapevine” was extended to the entire roadway. Why this was done is still unclear. Even Caltrans called it the “Ridge Route” when I-5 was completed. So, if you want to call it proper – call it Tejon Pass, when being specific to the actual pass, and the Ridge Route when referring to I-5 from Castaic to Grapevine. While you’re passing through Grapevine Canyon, be sure to spot the wild grapevines that still grow in the canyon. Names may change, but the name Ridge Route should live on. It applies to I-5 better than “The Grapevine” ever will.

Site News

Well, Unbeknownst to be, this site wasn’t being indexed by Google and had effectively disappeared from searches. Now, after 24 years of work, being the first website to cover many things (the Ridge Route, US Highways 6 and 99, Geology in Santa Clarita, Wineries in San Diego County) it was rather disheartening to not even find the site after multiple pages. I think I’ve corrected this problem, only time will tell. I will not let all this work just vanish because of an error that can be corrected. I have also created a new poll for the site to help determine how people are getting to it.

Owens Lake, once a fairly large lake at the southern end of the Owens Valley, dried up after the water from the Owens River, its primary source, was diverted into the Los Angeles Aqueduct. That aqueduct, engineered by William Mulholland, was officially opened on November 5, 1913.

Shown here, the shorelines of the former Owens Lake are visible in the distance, rather looking like rings in a bathtub. The lake bed, after the lake was gone, became one of the largest single sources of particulate matter pollution in the western United States. Mitigation efforts, required by court decree, have helped a great deal but are still a far cry from the lake that once had steam boats crossing it.
