  This field trip was to be a two part event out at the Lake Pleasant area.  We first were to visit the geode location and then travel beyone the lake to a site to collect shattuckite and common opal.

We are shown here waiting for the trip leaders to determine where we are located in relation to the geode site.  After much discussion about the directions, we turned around and headed back down the road to where we had passed the correct parking area for the geodes.

Before we departed for the geode site, I snapped a picture of the great senery!

Notice the rock exposure on the side of the hill on the left.  This is the landmark to look for!

The ground is covered with all different sizes of thundereggs!


Some example of the Thundereggs from this location.  Notice the "nobbie" surface and the chalcedony and common opal protruding from some of the openings.
