An Attempt to Account for Natural Sunlight in the Caves of Chaos

Factors to consider: location of sun, elevation level, intervening foliage

I've probably made several mistakes here, since I've never attempted this kind of analysis and lack formal training as an artist or an astronomer.  However, I will tentatively conclude that if exploring the Caves first thing in the morning, Cave J looks particularly inviting.  A little later in the morning, Cave I, particularly the left branch at the entrance, becomes a good choice.  At least, based upon ambient lighting alone.
