| The best times would be early morning or late evening (depending on the terrain etc. of course) when the low sun will cast longer shadows. If I suspect something is there but can't be sure from looking or touching, I just flash the surface from the side and review it on the camera. I'll usually do this for any suspicious looking surfaces around an existing panel since it doesn't cost anything with digital! It can be frustrating at times because you can often find what looks like an excellent candidate but which turns out to have nothing only for something to turn up on a more marginal surface nearby. There's no pattern that could let you judge whether a particular surface would have been chosen or not depending on the type or texture of a surface. Prepare to spend hours staring at rock after rock!
