MARQUETTE — Driving west into Marquette along U.S. 41, passers-by come across a stone structure that resembles an igloo on the Iron Ore Heritage Trail.
Were those curious aware at one time the kiln was used to burn wood into charcoal which fed blast furnaces that converted iron ore and limestone into pig iron during the late 19th century?
After the last of the 43 Carp River kilns collapsed in a heavy wet spring snowstorm in 2016, the historical sandstone structure has been resurrected and was officially turned over to the city of Marquette Monday during a ceremony.
