This wooden coal tipple is one of the last historic wooden coal tipples left in the West and is an example of mine engineering technology used in the late 1800's and early 1900's. It consists of two distinct parts: the coal bin, the large gable-roofed uphill structure, and the downhill chutes. The gable-roofed structure received and stored coal for sorting and loading. When a door at the bottom of the bin was opened, the tapered funnel-shaped floor gravity fed coal into the chute system. The chutes were constructed to sort nut-sized, egg, and lump-sized coal as it traveled down the slope by gravity. Three transloading chutes dumped the sorted coal into train cars. Before sediment eroded from the hillside above, there was sufficient room under the two lower bays for train cars, while a third track was loaded from the chute on the south face of the tipple. The remains of a catwalk are visible on the east side, where the operator would coax coal down the chute by pulling and poking it with a handled tool.
