I think I mentioned before that my great grandfather was a miner in Nevada in the late 19th century. He mined two forms of copper ore, green malachite and blue azurite, copper carbonates with formulas Cu2CO3(OH)2 and Cu3(CO3)2(OH)2 respectively. For some reason, our family collects rocks. These were gathered on the mountain where my great grandfather lived and where my grandfather and his two siblings were born and raised. We have recently thrown away a lot of rocks that were in my mom’s basement but we kept a few that were particularly nice. Cathy put some in this bowl and they are outside our front door, where the bowl has filled with rain water, which I think makes it especially nice.

Malachite and Azurite
Sometimes when you travel, you pick up souvenirs. You might buy a post card and you’re almost certain to take a few (or a lot of) photographs, which for most of us really help to keep memories alive. We can look at the photographs and remember what it was like wherever we happened to have been. Or we might buy a small object in a store or at a market to remember the trip by. In our family, we sometimes pick up stones. Sometimes they are selected because they’re a particularly pretty color or have a nice pattern on them. Other times, it’s their shape or the smoothness of the surface. Some here—the green one at the top and the bluish green one on the right—are from the Nevada ghost town where my grandfather was born, 135 years ago.
C&O Canal Rocks
These rocks are south of Pennyfield Lock on the C&O Canal. The photo was taken on the same walk as the previous one of the great blue heron. It’s an HDR composite photo made from three images taken with different exposures. This allows the camera to capture more detail in the shadows and highlights than it would normally be able to do. As amazing as our modern digital cameras are, they still have a ways to go before they can handle the extremes of light that we take for granted.
When we bought our house, the outside portion of our air conditioner was on the back patio. I’m not sure who would ever think that was a good idea. Someone who never sits on the patio, I guess. When we replaced the furnace and air conditioner, we had it moved to the end of the house so we could actually sit outside in the summer and hear each other talk. The concrete plinth that the unit used to sit on is still there and is a sort of stage for assorted bric-a-brac. Rocks, shells, bones, and antlers make up the bulk of the collection.
