1. Grew stands on the edge of a small island sitting on an ice-covered bay. To the south is an approximately 700-meter-high mountain that is part of a coastal range stretching to the continent's edge. The bay leads northwest into an ocean.
2. The island and mountains are composed of regionally metamorphosed, ultra-high-temperature (near 1,000 degrees Celsius) rocks of Archean age, some as old as 3.8 billion years. Certain rocks exposed in the mountains contain sapphirine with quartz and osumilite. The mountain is scarred by post-metamorphic dikes of Proterozoic age.
3. The area is in a region discovered in 1831 by the Englishman John Biscoe.

The photo was taken by Chris Carson in Enderby Land, Antarctica. It shows Edward Grew of the University of Maine standing in the foreground and Priestly Peak and Amundsen Bay in the background. The location is about 50 miles southwest of Mount Biscoe and Cape Ann.
Each month, the first three readers to identify the location will receive the Glossary of Geology. The first 10 will receive a Where on Earth? T-shirt.
