This
is a schematic map of the over 3,300 stone sites currently in my
database, in 100 km blocks using the UTMs for boundaries. Note the
clear separation between the Southeast and Northeast data, and also the
absence of sites on the coastal plain from Georgia to Delaware. More
data is coming in, so this shouldn’t be considered final – but it does
give you an idea of how the sites are distributed.
Just this morning I was wondering about how features are defined: http://wakinguponturtleisland.blogspot.com/2013/03/coming-to-termsstone-definitions.html
ReplyDeleteNow I guess I need to know how a site is defined - I live by a village site by an agricultural floodplain by a fishing site connected to a bunch of other types of sites along streams and trails bordered by stone remnants that all seem to have been connected to other sites etc. What's a UTM boundarie?
I think topo map coords are UTM.
ReplyDeleteI always define sites as separate when you cannot see one from the other.
This map makes me feel dumber then a rock in a rock pile.
ReplyDeleteWikipedia believes that: he Universal Transverse Mercator (UTM) geographic coordinate system uses a 2-dimensional Cartesian coordinate system to give locations on the surface of the Earth. It is a horizontal position representation, i.e. it is used to identify locations on the Earth independently of vertical position, but differs from the traditional method of latitude and longitude in several respects.
ReplyDeleteThe UTM system is not a single map projection. The system instead divides the Earth into sixty zones, each a six-degree band of longitude, and uses a secant transverse Mercator projection in each zone.
Does this data coincide with where there are active groups exploring? Putnam County looks pretty active, as does Alabama/Georgia. Also my are in Mass. and west of here in the upper Hudson. I do know a group of people in each of those places.
ReplyDeleteSo it is a bit of a chicken-and-egg problem: no sites to find, or no one looking? or no one looking because there are no sites to find?
It is my understanding that Hoffman's database comes from NEARA site files, State Archaeologists office files for the various states withing the study area, site files from researchers like Peter Waksman, the Gages, Doug Schwartz, and others. Some of the high site #'s represent ongoing intensive site survey work in certain geographical regions. Some regions are certainly under-represented due to limited exploration. Other factors that may come into play are the availability of stone in a particular area, the impact of urbanization (i.e. site loss), and mis-classification of sites as agricultural.
