WTHA2: is closer to the equator, the only visible shaddows appear to exgagerated by the nearby creakbed. I Estimate summer, between 0 degrees north and 45 degrees north.
WTHA3: No visible shadow detail, hint given is "south america"
WTHA4: Cloud shadows suggest morning near the equator, likey between 30 degrees south/north. Hint was "Africa", my analysis narrows it to north Africa.
WTHA5: Shadow detail is hard to see; appears to be another morning image. Hint was Asia. I think I can narrow it to between 22 south and 45 north, which eliminates most of Russia.
PS: voted both "Yes" and "No" in the poll
I think your shadow information is irrelevant...can you explain it further?
