Satellites Expose 8,000 Years of Civilization

ananyo writes "By combining spy-satellite photos obtained in the 1960s with modern multispectral images and digital maps of Earth's surface, researchers have created a new method for mapping large-scale patterns of human settlement. The approach was used to map some 14,000 settlement sites spanning eight millennia in 23,000 square kilometres of northeastern Syria — part of the fertile crescent of the Middle East. Traditional archaeology has focused on the big features such as cities or palaces but the new technique uncovers networks of small settlements, revealing migration patterns and sparking renewed speculation about the importance of water to city development."

    However, I have heard a number of stories from buddies who got into archaeology and did some fertile crescent digs; that there is an interesting demographic who has a real, visceral attack of this problem:

    Your sharper breed of American christian fundamentalists, coming from an area where any evidence of human habitation is either a few hundred years old, max, or fairly subtle and 'radiocarbon dating/the flood/etc/etc. awayed' during their growing up decide that they want to do some biblical archaeology. So, off they go and they find themselves grubbing through masonry that just oozes OLD in a much more immediately dramatic way than some of the subtler isotopic dating results or other inferrential work does. Apparently some of them find it quite traumatic or transformative: The "This wall/building/house/whatever had already been standing for at least a few millenia at the point when God is supposed to have created the earth" thing is much more potent than the "Some scientists say that C14/C12 ratios in cave charcoal suggest timeline... yaddda, yadda..."

    I once used the satellite view of Google Maps to look for old train tracks that have been torn up and gone for decades. It's actually pretty interesting. If you go out and visit spots where the tracks used to be, you can't see anything out of the ordinary. But a satellite shot clearly shows the "scars" of where the tracks used to be. Where they cut through forests, the trees are a little shorter. The soil in farm fields is colored differently. Roads bend to intersect the track at a right angle, things like that.

    Here's a good example in Washtenaw county. You can see the "ghost tracks" going southwest/northeast. If you follow them northeast, you'll see that a new subdivision was built on an area of land that they used to cut through. Curiously, the developers built no houses where the tracks were. Instead, they added footpaths, gave some houses larger backyards, and left "gaps" where houses could have been built. (I'd love to know why this was done. Any developers in the audience?)

    You can follow the tracks southwest as well, but eventually you get to a region where the images were taken with a different satellite at a different time of year and the loss of contrast makes the tracks impossible to follow any further.

      That particular run goes reasonably close to my house. The totally apocryphal explanation for those "tracks" was that Norfolk Southern, or whatever the iteration of the railroad was named at the time the development was planned, bought the rights to that land with the plan of bridging Ford Lake (why they would I have no idea. That'd be an expensive bridge at that point) and connecting to the auto plants (at the time GM Hydramatic and GM Willow Run Assembly), the Airport (Willow Run, with the idea of being a sort of intermodal hub) and the NS line just north of the airport that runs East - West.

      In the end they backed out on cost and opted to serve both plants from the East - West line, even though it necessitated a longer trip to connect. (Incidentally, Amtrak will eventually own that stretch of line all the way from K-zoo to Detroit, adding to their longest continuous track track section outside of the Northeast corridor.) That ghost trail was also part of the line that crossed US-23. Not under, crossed. A two lane divided highway that at one point had a live rail crossing.

      Interestingly, the http://www.historicaerials.com/ images don't show the 'ghost' trail until 1963. The 1955 images don't show anything. NS also owns property much closer to bridge road (take Textile west from Bridge, look to the right. You'll see a large section of land with NS branded 'no trespassing' signs).

      Are you sure it's a former trackline? Looking at how clear-cut the trail is through some of the wooded areas, makes me wonder if there isn't an oil or natural gas pipeline of some type running there. Thus the reason for not building over it, and keeping the land clear of trees. I also find it odd that there is no elevated trackway present anywhere along the several miles I looked at. Also indicative of a pipeline rather than a railroad.

      In fact go north to the subdivision where they haven't built over the trail. And use street view on E Bemis Road right where the trail crosses into the subdivision. If you look to the north you can plainly see the Pipeline warning poles, placed next to the road on to either side of the trail. There are also such poles on the south side of the road but they don't stand out quite as clearly. It's a pipeline not a railroad track.
