About 4 years ago I was laying on my back on top of Mt. Whitney in central California.

A satellite moving south to north went directly overhead. I'm assuming it was a satellite as there was no sound and it was very fast and seemed very high.

(I realize China Lake and Groom Lake aren't far, and they have some weird things. I've watched practice dogfights from Mt. Whitney a time or two. Even saw two F-16s zipping by underneath me on the west side of Whitney. That was daylight.)

I remember trying to figure out what that might have been when I got back, couldn't find anything in the 10 or 15 minutes I tried.

But someone here would know. What goes south to north?
Very nearly directly south to north.

Thanks for whatever attention anyone can give this.
