Mass Mine

“As the copper hunters descended down upon the upper peninsula they found themselves traveling across lands occupied by the Anishinaabe, a native people that came to the Lake Superior lands generations earlier. Those early industrialists were particularly intrigued by the Anishinaabe culture and language, and utilized native terminology to both describe the land they were exploiting as well as the mines and machines they were constructing. Thus many mines have Anishinaabe names, including a small rather insignificant mine deep within Ontonagon County known as the Ogima.”

The Missing Link

We’ve managed to explore a great deal of ruins at the old Ogima shaft, otherwise known as the Mass C. In addition to the shaft itself, we’ve found the remains of its impressive sized rockhouse, dry house, and even a boiler house. Yet for all these discoveries there was a …

Among the Coal Fields

Stepping away from the hoist foundation we discover a scattering of concrete footings surrounding the building. These footings are adorned with pairs of iron bolts and are arranged in parallel lines stretching out from the building. We’ve seen these types of blocks before and they are almost always serve one …

On the Inside

After checking out the Mass Mine’s Hoist House from its outside, we turned our attention to what could be found inside the walls. Luckily for us it the foundation wall on the building’s south end were much lower then the rest, allowing us to simply step over it to enter …

Sitting atop a rugged bluff deep within the interior of Ontonagon County sits the Mass Mine, an industrial endeavor that operated under various legal identities for close to seventy years. If a mine’s success can be determined by the legacy it left behind, then the Mass could be considered a …

A Mass(ive) Rock House

The Mass Mine sits atop a massive rocky bluff overlooking the quaint little town of Mass, and as such was in a rather precarious position in regards to its accessibility by rail. THe mine’s shafts were sunk right up alongside the face of the bluff, and provided no room for …
