There are some beautiful photos and you can view them by category. If you have extra time on your hands you can peruse all 15,500 entries as well!
The prizes awarded were:
First Prize: A 10-day Galápagos National Geographic Expedition for two
Second Prize: A 7-day National Geographic Photography Workshop
Third Prize: A 6-day cruise on a Maine windjammer schooner for two
7 Merit Prizes: $200 gift certificates to B&H Photo and a matted and framed print of your entry
I think I'd prefer the 3rd prize over the 2nd prize!
