Gravestone Project- First Attempt

I dragged my poor husband out to Sharp Cemetery after work on Wednesday to attempt my first set of data for The Gravestone Project.

I chose that location over Killeen City Cemetery because Sharp Cemetery is smaller and more remote, which means there were likely to be fewer people to be offended by and/or ask awkward questions about what those two crazy people were doing to the gravestones with all those weird instruments.

The "new" GPS (actually a fifteen-year-old Magellan GPS 2000 in suprisingly good condition, which is very basic but does what I need it to do) works pretty well if you give it a minute or to to pick up enough satellites. I knew this already because I spent Wednesday morning at work playing with it, and I now have a partial GPS plot of the funeral home to show for it. Locations were easy enough as a result.

Determining the direction the gravestones were facing was also pleasantly simple despite the fact that I forgot to bring a compass (no excuse since I own three or four) thanks to the fact that Sharp Cemetery is coveniently laid out on pretty close to exact east-west lines (who needs a compass when you have a beautiful sunset because you put off the trip until too late in the day?) so all of the graves are facing either due east or due west, and it's not hard to tell those two apart, especially in the late evening.

Measurements were slightly more problematic. I had acquired a nice set of digital calipers on Amazon.com, and except for one afternoon of enthusiastic fiddling with them, I hadn't really spent as much time practicing measurements as I should have before actually going to the cemetery. I quickly discovered that the digital calipers were technically easier to read than the analog ones I had used back in grad school, but slightly trickier; I must have measured the same spot on one particular marker five or six times, because I kept getting different readings on my calipers.

Determining ground level- which is important in the placement of the measurements, and which also has to be recorded if you're measuring a gravestone on a pedestal, which most of the marble ones at Sharp Cemetery seem to be- was also a little tricky thanks to uneven ground and thick tufts of dried grass. I had forgotten something vital about field work of any sort, in any discipline- it's never as cut-and-dried or neat as the plan says it should be.

By the time we had to leave, after less than an hour of working time- we were late to our planned dinner anyway- we only had one set of measurements which I didn't quite trust, and I was grumpy, frustrated, and disappointed. My remarkably patient husband chalked it up to a learning experience and made a few helpful suggestions, mostly centered on practice, instruction-reading, and a few more items of equipment, like a small level.

With that in mind, I'm hoping to make another attempt this weekend, hopefully with better and more useful results.

The Gravestone Project

All that nonsense about not doing any more cemetery stuff until the weather gets cooler pretty much went out the window last week when I discovered The Gravestone Project, courtesy of EarthTrek (although I'd like to point out that I did admit that decisionw ould probably only last until I saw something irresistibly interesting).

For the record, I'm an enthusiastic, if recent, fan of "citizen science" programs in general, partly because they're a clever and cost-effective way for researchers to gather certain kinds of basic but important data, partly because they're a really great hands-on public relations and educational tool, and partly because they're a nice combination of fun, worthwhile, and interesting (I'm working on a whole other blog post about the social and cultural implications of programs like EarthTrek, sites like Find-A-Grave, and other sites and programs that link online presence with offline task completion).

The Gravestone Project aims to plot global patterns in the severity of "acid rain" based on erosion of marble, which is particularly susceptible to its effects. This is accomplished by measuring marble gravestones and comparing their thickness at the base (which is less exposed to rain), the sides about midway up (which are slightly more exposed to rain) and the top (which is the most exposed), and comparing the difference in thickness (the amount of erosion, in other words). That difference, based on the age of the gravestone, lets the researchers calculate the extent of acid rain erosion during that time period in that location.

It seems like a worthwhile project, and I expect that seeking out marble gravestones and taking the measurements will give me something additional to do on cemetery outings, along with Find-A-Grave requests and my own iconography studies. If anyone is already involved in Find-A-Grave, this might be something worth considering.

I got a nice shiny set of digital calipers on Amazon (for about ten dollars including shipping); they just arrived in the mail today, so I'm all set to get started. I'm excited; I haven't measured things in the field since graduate school.
