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.

Send answers for the November 2002 Where on Earth? contest, which appears the print magazine, to Geotimes by Nov. 25 (or postmarked by this date). From those answers, Geotimes staff will draw the names of 10 people who will win Where on Earth? T-shirts. And from those 10 names, we will draw the names of two people who will win a Brunton compass.

1. Part of an area called “sacred waters” in the local language, this spring is 25 kilometers south of an island city founded in the 14th century.

2. The bubbly, hot spring pool derives its name from the character of its thermal waters. Fed by groundwater, it sits in a hydrothermal eruption crater that formed about 900 years ago.

3. Orange precipitates visible around the rim of the pool are rich in arsenic, antimony, mercury and thallium, and contain ore grades of gold and silver. This suite of elements highlights the fact that this geothermal system is an active analogue of systems that form epithermal gold deposits in volcanic arcs.

Name the feature and its location.
