Photo above:  The view looking East from the Pittock Mansion in Portland's West Hills 
to Mt. Hood standing above the Cascade Range.  It is this volcanic nature of the Pacific Northwest that gives the region so many Rockhound wonders such as Thundereggs, 
Petrified Wood, and Fossils!

These are some of our favorite sites to learn more about geology, earth science, rockhounding, minerals, lapidary, and jewelry.
