Where is the Great Basin?

The question isn’t simple. You’d think the Great Basin was the area of the ancient Lake Lahontan or the area that drains into the Carson Sink. Links: Here Are a Few, But Great, Great Basin and Great Basin Divide Links provides a few other thoughts about the boundaries of the Great Basin. A Google Earth image is provided:

Google Earth image of the West with a lot of lines. The Great Basin divide according to me is in magenta, wrapping around the Great Basin. Note the two possibilities at Pahranagat Lake, and no Salton Sea.

It seems that the Sierra Mountains define the western border, The Snake River drainage is to the north and the Colorado River drainage defines the eastern and southern boundaries for some. That gets into a lot of territory over a wide range of elevations with most of it desert of one sort or another.

The blog has some interesting exploring of Nevada with a geologist’s point of view. It is a good resource for touring the Great Basin and getting a better handle on what you are seeing.
