Megan has long been a rock collector. She likes to pick up a rock here and there whenever we go to a park. The hobby seems to be infectious. I would pick up a rock or two. My first trip with Georgia Mineral Society is to collect the lace agate at Summerville, Georgia. What a perfect location! The subject for first week of Alan’s social science is the five geographic regions of Georgia. Summerville is located in the Ridge and Valley region of Georgia (Snellville is located in the Piedmont region).
The lace agate collection took place at a private quarry just outside of Chattahoochee national forest. We don’t have any specialize sledge hammer or chisel for rock hounding. All we have are garden shovels, house hold hammer and garden border chisel but that’s good enough for the site. We do take the advice of bringing extra bottle of water. It came in handy when we need to rinse the chalky white chert from the rocks – most rocks here are covered with white dust called chert. Fortunately, we don’t need much digging tools since most rocks are one the surface. The quarry has piles and piles of rocks that we can simply pick from the surface.
We spends hours washing and brushing the rocks after gone home. The patterns of the rocks stands out after cleaning. Here are some macro shots of Summerville Lace Agates with Olympus stylus 7010 snapshot camera in super macro mode.

Varieties of lace patterns:
Summerville Lace Agates are beautiful rocks. They are created with unpredictable patterns, geometric shapes and colors. The quartz on the agates give the rock extra sparks. The rocks are very pretty even without additional cutting or polishing. We are going to display some in the original form and polish some with rock tumbler. That’s will be our next project.
* Photos are taken with Tucsen 3.0MP CMOS microscope camera from Ample Scientific SM Plus Stereo Microscope. The color tones of the photomicrograph is somewhat blueish because of the LED illumination while the macro shots with the Olympus Stylus 7010 are using the incandescent lights which results in yellowish color tone.
