The white agates scattered over the area of Fourth of July butte are in form of irregular/geometric nodules (filling in fissures/veins) and rarely amygdaloidal nodulesand "Chimney Beds" is one of few more productive locations. The "Chimney Beds"  refers to the chimney ruins on the eastern side of the butte, and the diggings are around the buttes where the agates can be found by just patiently walking around or digging to find any irregular shaped nodules.  The agates are almost always white to gray, but some have been found with lavender, pink, red, purple and blue hues. The shadowing effect is usually strong in the well-banded agates, and some agates contain reddish plume structures and pseudomorphs. The agates are found along the layer of rocky debris just below the surface and above the clay layer (in basin) or heavily weathered greenish basalt bedrock (on the sides of the hills). I did not find anything in the clay layer and there are some agate veins in the weathered basalt bedrock. It will take a great deal of shallow digging to find some.
   NOTE: As of December 2008, there is a private claim on it and it's not known if it's still active today.

Rough Appearance: Irregular and Geometric shapes with white to clear agate showing.
