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.

Submit photos for Where on Earth?

For the June issue, the first three readers to identify the location pictured in the current print version of Geotimes received the Glossary of Geology.  The first 10 will received a Where on Earth? T-shirt. Beginning in July, the first two readers will receive a Brunton 8099 EclipseTM compass and the first 10 will still receive a T-shirt. Please note that all contestants are eligible to win one compass per year.

June clues & answer:

1.  More than half a billion years ago, this cliff was a reef, and the gem-like lake in the foreground would have been buried deep in muddy sediments.

2.  The well-preserved remains of some wonderful animals were found at the base of the cliff in 1909.

3.  Only a few years after that discovery, the area -- now a park -- served as a World War I internment camp for natives of the Austrio-Hungarian Empire.
