Re: Re: [Texascavers] Almagre, TAMS sat image, an explanation

[tbsamsel]

If you go to Google Earth, the area on the W side of the road has a photo there of Presa la Sauceda (an earth dammed reservoir). It looks like a digital artifact where there is overlap in edgematching of the satellite images from INEGI. There seems to be a splice there..

Here is my best guess at a serious explanation for what's in those satellite photos. Admittedly, it is only a slightly educated guess, but it seems plausible, and if anyone has a more likely explanation, I'd like to hear it.

Suppose you were a farmer/rancher in an area with lots of undeveloped land, and you would like to grow crops on a relatively small portion of that land. You would like to pick an area likely to have adequate ground water for the crops, even during the dry season, without you having to invest in an expensive irrigation system. You can't afford the initial equipment and drilling costs or the ongoing energy costs of pumping large quantities of irrigation water from wells. You have no nearby river or large lake to supply irrigation water. Most of the available land is forest or grassland, where, without irrigation, the rainfall might or might not be sufficient for the crops you'd like to grow. You'd be gambling on the weather if you planted crops there.

Your land does, however, include a couple of natural ponds, which collect water to a modest depth during rains and which dwindle to a very shallow depth or become little more than mud holes during dry weather. Even during very dry times, however, these ponds still contain enough water to keep the soil moist on the pond bottoms. In this case, you might convert these ponds into good places for growing crops simply by rearranging the soil on the pond bottoms. You dig a crisscrossed array of canal-like ditches and pile up the soil between these ditches to form a number of small rectangular islands, where you plant your crops. During rainy times, the ditches fill with water, but the islands remain high enough to keep the crops from flooding. During dry times, the water level drops in the ditches, but there is still enough water in the soil to provide adequate moisture to the roots of your crops. From the air or a satellite view, you still see the natural irregular outlines of the ponds, but inside each pond, you now see a crisscrossed network of canals and rectangular islands. These islands normally are green with crops, and the canals might or might not contain visible water, depending on how much rain has fallen lately.

I don't claim to be any expert on this, but from what I've heard and read from time to time, I believe that archeological evidence has been found indicating that agricultural techniques similar to this were used for a very long time (many hundreds or even thousands of years) by native people in portions of South America, Central America, and Mexico. Perhaps some of you archeologists out there can provide better information about traditional agricultural techniques and can give us your thoughts about whether this explanation of the satellite photos makes sense or is just all wet.
