This is the "go to" general page for geological sources, resources, and information.  For now we can use it to store information before it's sorted any further or lost to indexing.

Weather is the Speed of Life.
We consider the interrelationship between geological and biological processes.

Volcanic Tomb for a Granite Range.
We observe the slow reemergence of ancient hard granites as thousands of years of erosion scour the soft volcanic material off the buried granite landscapes underneath.

Recent Discoveries.
A short set of links to a series of articles explaining the recent evolution of our understanding of the complex geology of the Sierra Nevada Mountain Range.
