The National Geographic Photo Contest for 2012 ends today, November 30, but for procrastinators that thrive on deadlines, there’s still time to enter! The contest officially closes at 11:59:00 p.m. US Eastern Time. This post features another small sampling of the entrants. (We featured another selection in an October Big Picture post.) View galleries of the thousands of entrants, from which an overall winner and winners in each category of People, Places, Nature will be chosen.
