Where on Earth?
Do you have slides and photos you've collected from field work or vacations?
Every month, we'd like to feature one of your photos from anywhere in the world and invite other readers to guess where it was taken. Look every month in the print Geotimes for a new photo. Following are clues, answers and winners from past issues.

The first three readers to identify the location pictured in the current print version of Geotimes receive a Brunton 8099 EclipseTM compass and the first 10 will  receive a Where on Earth? T-shirt. Please note that all contestants are eligible to win one compass per year.
