Today’s theme for the 2009 Challenge is Stone.

Stone has been used as a building material throughout history. See what you can find today that contains stone. Sculpture? Walls? Stones in a creek? It’s up to you!

Once you’re ready to submit your work to Flickr, you’ve got to do two important things. First, make sure you tag your photos correctly; “2009challenge″. Also, if you haven’t already, join the PhotoChallenge group on Flickr. Then, submit each day’s photo to the group’s pool.
