Display your own piece of Lafayette coal mining history with a reproduction Simpson Mine progress map showing Old Town Lafayette’s underground mining passageways. This 1921 map, drawn by draftsmen working for the Rocky Mountain Fuel Company, shows where 12-feet seams of coal were removed 250-feet below ground. The Simpson Mine operated from 1887 until 1926. The four-color reproduction is 72″ wide and 36″ tall and is mounted on foam core backing. Offered for a limited time at $199 plus tax. This is a rare item that you won’t find anywhere else. (Sorry, but the foam core version is for local — Boulder County — delivery only. Larger sizes available up to mural size. Please contact me if you’d like to purchase an unmounted version of the map.)
