We've really had too much snow to be able to see any rock piles. I've managed to get out a couple of times to "the bowl" and just observe, rather than explore.
Yesterday I hiked up to the U-shaped structure to try and catch the sunset.
I don't have any recent pictures of it, so here's one from over a year ago. In this shot, I am facing the opening:
Here's what it looks like covered in snow, but from the opposite view, so that I'm standing behind the structure, overlooking the opening, as you would be if you were sitting in it.
What a gorgeous view from up there! You can see the winter sunset just off to the left a little bit, right at the horizon. The opening heads due west, so it does not face the winter soltice sunset, but I have a hunch that March 21st might be a good day to check this one out again!
Incidentally, if you're wondering what's on that mountain range over there in the distance, you can click here and here for a little peek.
And here's one more look at that sunset. If you click on this photo, you can see that it overlooks "the bowl" from about the center to just off to the left.
