I guess the western mountains don't fit as well as the older eastern ones.

Food for thought.

Verde Valley Field Trip

Last weekend we had another amazing field trip lead by Paul Lindburg. This one was on the Verde Valley Geology. Paul puts on a great trip and explains the geology to all levels in the club-- both the professional geologists and the enthusiast proto-geologists learned from his explanations. More than 24 people showed up for the all-day venture from Jerome to Page Springs.

We will have one more trip in his series -- the Sedona /Oak Creek Canyon section. More on that trip later.

Hot news from USGS

The USGS released a fact sheet on the Geothermal Resources. If they were near the big population centers we could have lots of power and hot water for everyone -- as they do in Iceland.
