We've patiently avoided the remains of Fort Pike's two hotshot furnaces until now...I hesitate to say anything about saving the best for last, but I am particularly fond of hot shot furnaces (Click here for proof of this statement). The only other American starfort with two remaining hotshot furnaces to the best of my knowledge is Fort Knox in Maine, but as Fort Pike's furnaces were earlier examples, they're...weird, at least compared to the standard American hotshot furnace design that had been developed by the 1840's.
