Old State 136 near Keeler, CA

The Owens Valley in Inyo County, California is home to many fascinating highway relics. One road in particular toward the southern end of the Owens Valley southeast of Lone Pine, State Highway 136, had a very unique and rare feature – old railroad grade crossing markings. Until 1964, it was known as State Highway 190 and was realigned quite a bit between the Owens River and Keeler in the late 1940’s and early 1950’s as travel to Death Valley became more popular. Most of the old alignments are still traversable today, complete with original paving. The longest intact section is known as Dolomite Loop Road and runs between the Owens River bridge to just north of Swansea.

These crossings were still in use until the whole line was abandoned in April 1960. The markings themselves likely date to the 1940’s. They are made of a large X and an arrow pointing to the crossing itself.

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!

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.

Earthquake UPDATES – Mw 7.1 near Ridgecrest

Well, that was strong! I felt it here in San Diego. First time I felt my building sway and it shook for a while. USGS is now reporting the quake as a Mw 7.1, which is 11 times larger than the one yesterday. This, assuming a larger one doesn’t happen, has also been deemed the “main shock” and the 6.4 was the “fore shock”. USGS and Caltech are a bit slow right now. If you felt this one, please let USGS know once their servers are not slow or not working. They need your help!

From Caltrans and CHP, damage reports are coming in of rockfalls on 178 in Poison Canyon, a sinkhole on 178 near the Trona Pinnacles turnoff, and buckling up to 4 feet as well as large cracks in other areas. Do not drive fast through any of the earthquake affected areas. Also be aware that rockfalls will be likely in all the local mountain ranges, so be careful. State 127 near Ibex Pass is covered with rocks, and that is a fair distance away from the epicenter.

US 6 on US 6

In mid-October, I went on a road trip, part of which covered a section of US 6. It was the first time I had taken US 6 on a motorcycle, let alone my US 6 plated one. I felt it was a good opportunity to take a photo.
