Below is an idiosynchratic mix of sites that relate to the objectives of the SWI.
STONE WALLS NATIONALLY:
The Stone Foundation, based in Santa Fe, New Mexico is diriected by Tomas Lipps. It’s a great link to stone walls outside of the New England region. Professor Thorson will be speaking at their national meeting this summer in Acadia National Park, ME on August 20.
The founder of Monterey Masonry, Mark Mendel and I have become collegial associates. We have worked together on several occasions. Though I cannot endorse his stone work on this public website, I can offer his company as an example of a mason.
After decades of professional photography the photographer Jack McConnell became “obsesssed” with stone walls. We’ve become friends. He has a popular postcard book in stores nearly everywhere, and has done gallery shows on only stone walls.
WHAT KIND OF ROCK IS THAT?
The best aceess is to go through your state’s geological survey, which can be found from an alphabetical list at the Association of American State Geologists.
Know where your stone comes from. Was it stripmined from an old wall? Some quarries are are no more than staging areas where scavenged and stolen rock is sorted, high-graded, and sold to unsuspecting buyers. Goshen Stone is one of the good guys out there. Their mica schist, after only a few years, looks as as good as it gets. There are plenty of other good companies out there. Just beware of the bad ones.
LANDSCAPES FROM SPACE
The National Geophysical Data Center (NGDC) is a federally maintained archive of information about the nation’s physical landscape From this site, you can find shaded relief maps of anywhere. Try picking a state, then zoom in on your town, then look at a color shaded relief map of its topography.
