John, what incredible images- the ice towers and the caves! The more I learn about and "see" of Antarctica, the more precious a place it becomes. I can only imagine standing there taking it all in :)We are on Christmas break now, but the day we left we checked on your progress and one student asked "how quickly can an ice tower form?" Keep those beautiful pictures coming! I hope you enjoyed a peaceful Christmas on "the Ice" :) Feliz Navidad, Lollie

Merry Christmas Lollie,Thank you for the kind words.  A large ice tower can take 10 -20 years to get to the size that you see.  And they are still growing!  
We had a very nice holiday.  Take care and enjoy!
Cheers,
John
