McMurdo Dry Valleys
![Map of the [[McMurdo Sound](https://upload.wikimedia.org/wikipedia/commons/9/9f/Mcmurdo_sound_USGS_map.jpg)
The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier.
The valleys are located within the McMurdo Valleys Antarctic Specially Managed Area (ASMA-2). Provided by Wikipedia
