I do not believe I have seen this Circa '42 Auto Club map posted here before - mostly because of its size. The accompanying quoted text speaks for itself. I would assume this to have been a very early '42 map, considering that other maps, or at least the kind that were typically provided by the large gas station chains, deliberately omitted landmarks that were of strategic importance, including race tracks, airports, oil refineries, and rail lines. Beneath that are assorted pics of implementation of blackout measures, ca/ '42. Has this topic been covered here?

On a side note, it is interesting (to me) (especially in light of the previous post about "Bimini Slough's" connection with "Silver Lake") to follow the the path of Silverlake Blvd. into Beverly Blvd and notice the curve where Beverly meets Rossmore. It is the same "sometimes-foggy" perennia-creek-golf course-estuary mentioned in the lost stream article.

"Dimout Zones, 1942

Navigating the curves of Mulholland Drive can be challenging enough in daylight. But during World War II, the U.S. War Department imposed dimout regulations on many roads--including Mulholland--that were visible from the ocean, requiring motorists to drive with their headlights off at night. This 1942 map from the Automobile Club of Southern California archives shows where dimout regulations would be enforced, explains Auto Club historian Matthew W. Roth:

In the fall of 1942, Auto Club cartographers and U.S. Department of War officials surveyed the coast of Southern California to define the "dimout zone," where motorists were required to turn off their headlights. Designed to thwart enemy vessels off the coast, the dimout would make it more difficult to navigate using onshore landmarks and would eliminate the backlighting of potential targets. Using the Auto Club's standard map of Metropolitan Los Angeles, the survey team marked those roads and highways where the dimout would be enforced. The blue and yellow markings indicate the direction from which the particular road would be visible from the water.
