More Rocks

Another thing about rocks—I warned you!—is the matter of scale.  When I go out jogging, it’s on pea gravel.  Some of these tiny stones are interesting.  Or, if you’re the romantic type and gave or received an engagement ring, that diamond is likely not to be massive.  I’m always reminded of this when I go to a mall, say, which has a floor full of fossiliferous limestone.  I think of the hours I’ve spent poking around creek beds and cliff faces for fossils, and here, laid out for thousands of square feet, is polished flooring floating with fossils.  Or when I walk into a bank, say, and see a counter made of labradorite.  I carry a small labradorite piece in my pocket that my brother once gave me.  I love the way it catches the light and reflects a beautiful blue color back to me.  Here it is in massive form where I’m trying to make a modest withdrawal.

Once in Wisconsin we went to Devil’s Lake for the purple quartzite of the region.  If you look among the tumbles you can sometimes find clear quartz crystals.  I’ve noticed that on rockhound YouTube channels that collectors are chuffed to find nice, if small quartz crystals.  They’re collectable.  But they’re also small.  Size is one of the reasons for not letting rock collections grow too much.  I’ve tried my hand at making small sculptures out of significant rocks.  I can see some of them on the landing window ledge from where I’m sitting at the moment.  They’re small, but heavy, and if we ever move, will require careful wrapping.  I’m not even sure what kind of rock they’re made of.

Rock identification is hard work.  I have a Moh’s scale set.  A streak plate.  A hand loupe.  It’s hard to use the acid test (vinegar will do) because the pieces are so small.  Identification is often destructive.  This might not be an issue if I had a ton of similar rocks to dispose of.  No, but when you have just a handful, and these had to fit in your luggage along with your clothes, making TSA agents scratch their heads, you’re reluctant to damage them just to figure out what they are.  So identifying the small rocks I have is difficult.  Online forums tend to be unhelpful in this regard.  Not even the color can give you certain answers.  Once I collected some jasper in a creek.  I could identify it because a large boulder clearly had jasper intrusions and I could compare.  The piece I took home, of course, was quite small.  Small, however, does not mean insignificant.

When I begin to lose my sense of wonder, the natural world grounds me.  I’ve been an amateur rockhound for many years and I sometimes wonder if it’s because I grew up poor.  The idea that you can just pick up something valuable on the ground has a treasure-hunting aspect to it.  Movers, I’ve discovered, dislike rock collectors.  My collection is quite small, and most of it not on display.  The danger is that I’ll be wanting to pick up more interesting rocks.  Like much of nature, rocks are amazing if you look closely at them.  And when the mania hits, it takes all my attention.  We all know that gemstones tend to be small, but perhaps it’s the fact that they look very little like their finished state in the wild makes them intriguing.

This interest was recently rekindled by a visit to the Lehigh Valley’s local cave, The Lost River Canyon.  As with most local attractions, it takes some time to get around to them.  We decided to go during the recent heat wave since caves maintain a constant temperature, generally in the fifties, and during the height of the wave the outside air temperature was double that of the cave thermometer.  Caves often have rock shops associated with them because being in a cave will trigger the rock-hounding gene.  And I suspect I’m not the only one to whom this happens.  Like many preserved caves, Lost River Canyon was an accidental discovery and was later purchased by a family that has been running it as a tourist attraction ever since.  I left inspired to find my rock tumbler and get it rolling again.

It’s difficult to say when or how such obsessions originate.  When my daughter was really into dinosaurs I started looking into geology.  The next thing I knew I was a member of the Wisconsin Geological Society and was going on field trips to collect.  When I lost my job at Nashotah House I seriously considered enrolling in a geology degree program, put off by the fact that calculus and chemistry were pre-requisites.  I was a hopeless humanities major and advanced math just doesn’t psit well in my psyche.  Part of me wonders if the fascination doesn’t go back to Genesis.  Geology was the science that tolled the death knell for any kind of literal six-day creation.  When this rock madness hits other interests can, if I’m not careful, be shunted aside.  It’s important to feel grounded.
