Looks good, having been there - think this looks quite nice. Good Point Jorge, the svastika is very common in some native american works, one of the local museums has a very nice Navajo rug with the same symbol. My guess is this one has been at the ruins long before any of us were thought about (let's say a few hundered years).
Think of it in the context of The Great Spinning Wheel of Life, not as hitler used it. I always enjoy images from sites like this as there are many things to ponder...
You don't have to beg Drew check Edward Curtis work from the area - it's been there over 100 years http://curtis.library.northwestern.edu/viewPage.cgi?showp=1&size=2&id=nai.01.book.00000173.p&volume=1
