Castles in the desert

 Kadizzle took a long motorcycle ride deep into the desert yesterday.  His first major stop was at an Indian site he previously found.  Wandering around the site he found a delicate piece of black on white pottery.  The quality of the little pot shard was amazing, both the delicate nature of the material and the painting with such thin precise lines.  Pondering the location it occurred to Kadizzle that these sites were evenly spaced along the mountain side.  It seemed like the old castle system in Europe where each castle controlled a certain circle of land. Exploring these sites it soon becomes obvious these people like to be on the high ground for good views of the area.  You were not going to surprise them. Kadizzle has puzzled, and puzzled about the walls of these dwellings.  Kadizzle has visited so many sites.  There is just not enough rock to have a wall more than three or four feet high. Another strange thing is all the walls seem to tumble the same way into a pile of rocks.  One possible explanation is the walls were held together by mud.  Over the centuries all the mud has washed out leaving nothing but a pile of stones.  Why were the walls so short? There seems to be two possibilities.  All the mud washed into the middle of the the rooms and now the floors are raised.  Maybe they finished the dwelling with wood or other material.  This year we have found more petroglyphs than in previous years.  Most of the rock here does not lend itself to markings.
