Another anecdote about U.S. Army Fort Rosecrans in San Diego, California.  
During my 1981 investigation of the 1796-1835 Spanish/Mexican fortification  
ruins of CA-SDI-12,000, my crew uncovered a burned U.S. Army building from  
1916-1922. In the burned floor was a smashed glass tank associated with various  
metal parts and several carbon rods. One of my 70-year old volunteers informed  
me he saw identical auto batteries in his grandfather's garage (the auto dated 
 from around 1912) and we carefully bagged the items as contributors to  
understand the feature. Had we separated the glass, metal and carbon rods, no  one 
would have understood the function later on in the lab. This little  
circumstance served as a lesson in historical feature documentation and guided  future 
lab and curatorial work for years.
