Talk about a trip you took out to Anza Borrego
Solstice Cave

Since today is the Summer Solstice, I took the day off work and headed out in the middle of the night to hike and scramble to the so-called "Solstice Cave" in the Anza Borrego Desert, a boulder cave with Native American pictograph paintings of the sun and other objects. One of these pictographs is supposedly illuminated at sunrise on the Summer Solstice, so I wanted to check it out. I had a high-lumen flashlight in addition to my headlamp, but unfortunately I still had difficulty finding the way at one point and arrived at 5:49am, 12 minutes after official sunrise. Looking at the angle of the sun to the various pictographs, I didn't think it would have illuminated any of them. But I waited around for a little over an hour to see if anything else would happen, until the sun had risen high enough in the sky that I didn't think the angle would allow it to shine into the cave anymore. None of the pictographs had been illuminated during my time on site. The number of sun pictographs (with none of them standing out as the main one) and their angles to the sun makes it seem unlikely to me that one of them could have been illuminated exactly at sunrise, but I'm disappointed that I wasn't there to know for sure. I wonder if anyone had any sources or information on this or if you've had personal experience or know someone who has. To me, it seems this cave may have been misnamed and doesn't have anything to do with the solstice. Perhaps this eastern facing boulder cave was just a good place for the Native American Shamens to watch the sun rise year round.

@dtoujours: Yes, I have been there and yes, it happens fast and depending on the exact date light will pass over different pictos. This has all been detailed in archeo docs. All it takes is a slight layer of smog or dust at sunrise and you will not see anything, you have a 50/50 chance from my experience.
Winter solstice, no, the sun is too far south and doesn't even hit the cave in the AM, just hits the draw outside.
