Please help me understand, If the city "fudged up" the SW corner by 10-12 ft, does that mean that the line visibly crossing the street indicating the south wall is incorrect, and that the planter which outlines the "alleged" location of the low barrack is not accurate? and that the entire SW wall/low barrack line needs to rotate slightly counter-clockwise (when seen from above) in order to show the actual south wall?
Mark: Yes, exactly..the current reconstructed line including the planter, as well as the line crossing Alamo street is off be a significant margin. Rick and myself measured this line starting at a point near the SE corner of the planter, and used Fox's archeological report showing the located footings of the low barrack, and retraced the foundation lines on the present day plaza. The actual footprint of the low barrack in relation to the present day planter is exactly as you suggested, rotated about 5 degrees (an estimate) in a counterclockwise manner. This places the actual SW corner of the compound about 5 to 7 feet inside the present Ripley's building, near the "Fat Lady" display.
Was this done with anyone's blessing? i.e. City, DRT? It doesn't really matter. Regardless of the circumstances it seems like information that should be documented somehow before it's too late, so that when the Alamo Restoration Project finally gets going, or the next San Antonio downtown renewal effort takes place, someone on a bulldozer doesn't blindly go through and obliterate it during construction. Where was this anomaly in relation to the visible south wall line?
Mark:Well, we documented our findings, and Rick documented his friend's GPR findings. Rest assured, when the restoration project gets underway, all of these details will be taken into consideration, and used.
I understand why destructive digging type of research is carefully restricted but something as benign as GPR should be done ASAP over every square foot of space not occupied by a building with a basement. And not just near the Alamo but out at LEAST 100 yards (or varas) from the Alamo perimeter. It just seems like a great project for some enterprising young History PhD candidate to wrap a thesis around, or professor to win tenure with.
Mark: I agree
Because of work done throughout the years it would probably be a real jumble of confusing data, but it would be SOMETHING to start with. I think the odds are against it making clear wonderful discoveries, but pretty good at generating questions and identifying potential areas for future research. In 10 or 20 years GRP will probably improve so that the early work can guide later work. It could all be done at night so that it didn't interfere with traffic
Mark: Again, I concur
Would it show where the foundation of the collapsed first chapel is? Would it show where the acequia had flooded? I guess we'll never know unless it's tried. I salute Rick and his friend.

Mark: That's a good question (regarding the first church's foundations) and I'll raise it with Rick. Of course, we'd have to have the DRT's authorization, even if we only run the GPR along the pedestrian sidewalk, but I wouldn't be surprised if they refuse us. The area in back of the church where the flooded acequia was, has been so disturbed over the years with various buildings built there, that I'm sure that area has been obliterated.
