Darryl Pearson found an interesting building in Lyons (Burleson County) inside a fenced area on Water Board property.  He estimated its size as 12 feet by 20 feet and about 9 feet high. One of the locals said it came from the Brazos River bottoms.  At this point, this is all we know.  It has a new tin roof and the walls are also covered with new tin.  This suggests to me that the original exterior may not be in good condition and the tin was added so that it can be used for another purpose such as storage.
