Owens Valley: Radio Astronomy in the Land of Sky and Stream
National Radio Astronomy Observatory

Though far to the west of the St. Croix antenna, the Owens Valley antenna has some similarities, in particular being in a remote location. The high mountains surrounding the valley mean that access to the region is only possible from the south, or through mountain passes. This also makes for a unique geography. To the south are the dry bed remains of Owens Lake, and further beyond is Death Valley. To the East are the White Mountains, which is home to the great bristlecone pine forest, and some of the oldest living trees in the world. Within the Methuselah Grove of this forest is hidden a particular tree that was seeded nearly 5,000 years ago.
