It’s cool that sunset/sunrise can make distant mountains stand out in silhouette even when they fade into the haze in broad daylight. The San Gabriels to the north, the Santa Monica Mountains to the northwest,
Signal Hill Palos Verdes* to the west, and even a small segment of Catalina Island to the southwest were all visible, though I don’t remember seeing any of them during the day today.
I remember riding in a shuttle back from LAX once before dawn, and I could swear that I could see the silhouette of the San Jacinto Mountains from Los Angeles. They’re out near Palm Springs. Not exactly something you normally see from LA.
*There’s a wedge-shaped hill that’s visible in the west from north Orange County on really clear days. Somehow I had it in my head that it was Signal Hill, but I noticed when I went to Long Beach Comic Con a few weeks ago that (a) I passed the city of Signal Hill on the way to the con and (b) the hill I can see from Orange County was still visible to the northwest from Long Beach. Thanks to Google Earth for helping me figure out just what hill it actually was!
