After close to a month I’m happy to say that its time to say goodbye to the Atlas Powder Plant and move one to the next exploration. But before we do I thought I’d through together a map of the ... More »
The mine’s of the Copper Country were generally self-reliant except for three things which they could not find along the peninsula: coal, iron, and explosives. For that time these items were tra...
On some maps it doesn’t exist at all, on others it is simply an afterthought dot on a nameless road. Driving along that road yourself you pass a sign that proclaims “Senter”, but see...
After the dynamite sticks were completed and boxed, they would then be loaded onto narrow-gauge rail cars for transportation over to the storage buildings at the other side of the property. Atlas had ...
While horse power in the rest of the country was quickly being replaced by the automobile, horses continued to serve the Atlas plant well past the war. Gas powered machines were too dangerous to have ...
Atlas Powder Company
In the process of trying to finish up this very long series on the Atlas Powder Plant, we bring you to the remains of the plant’s original NG house. The Atlas Plant had managed a perfect safety record for its ... More »
Continuing from yesterday’s look at various odd and ends at the Atlas Powder Plant, we start today with a look at yet another building – the Dope House. It was here in this two story structure that the pulp “filler” ... More »
The Atlas Powder Plant is enormous, covering over 1800 acres and consisting of over 240 buildings. Its easily the largest site I have ever explored for CCE; requiring over five hours, 400 photos, and (so far) 15 posts to cover. ... More »
Nitroglycerin had several bad habits, the least of which was its tendency to explode violently when agitated. Even more of a problem for workers at Atlas was the chemical’s seemingly natural attraction to their clothing. Even if you never handled ... More »
While horse power in the rest of the country was quickly being replaced by the automobile, horses continued to serve the Atlas plant well past the war. Gas powered machines were too dangerous to have around the nitro, so until ... More »
Due to the vast size and scope of the Atlas facility – over a thousand acres and a hundred separate buildings – an internal narrow gauge railroad was built connecting the various components of the explosive making process. While steam ... More »
After the dynamite sticks were completed and boxed, they would then be loaded onto narrow-gauge rail cars for transportation over to the storage buildings at the other side of the property. Atlas had three separate storage buildings (known as powder ... More »
Now that the dynamite sticks have been produced, the final step in the process is boxing the dynamite up in preparation for shipping, to be sent across the peninsula to various Copper Country mines. The Packing House sat at the ... More »
After being mixed into a Playdo-like consistency at the Mix House, the nitroglycerine was then loaded onto small rail cars and pushed by hand to the nearby Hall House. Here a series of machines would use the nitro mix to ... More »
After taking a look around on the inside of the Shell House, we decided to take it outside. The building was served by two sets of rails, one for each side of the building. From one end, the paper rolls ... More »
During World War II most civilian explosives plants across the country were drafted into military service, producing explosive shells and other military explosives for the war effort. The Atlas Plant at Senter, however, had never been converted to ammunition production. ... More »
After the nitro has been created and neutralized the next step in the dynamite production process is to mix the nitro with a fibrous filler material known in the biz as “dope”. Working much the same as sawdust, the dope ... More »
After being neutralized at the Store House, the nitro had to be then sent on to the Mix House, where it was mixed with the “dope” to form the gelatinous filler for the dynamite sticks. This was by far the ... More »
After the nitro was manufactured at the NG House, it was sent down along a rubber lined trough down to the next step in the process – neutralization and storage. Here the nitro was washed with a solution of sodium ... More »
The inherent danger in explosive making can not be overstated; nitroglycerin – the explosive agent in dynamite – is extremely unstable at high temperatures and highly sensitive to physical shock. The elevated and almost constant risk of explosion prompted Atlas ... More »
Of course being so far removed from the rest of Copper Country civilization insured that the Atlas Plant had to construct its own power house to provide the amount of electric power and steam heat a facility of this size ... More »
Though used as a commuter train for Atlas employees, the Copper Range trains also delivered the wide range of exotic supplies that an explosives plant required. These supplies included a wide range of chemicals used to make the nitroglycerine along ... More »
The mine’s of the Copper Country were generally self-reliant except for three things which they could not find along the peninsula: coal, iron, and explosives. For that time these items were transported here from elsewhere at high cost to the ... More »
On some maps it doesn’t exist at all, on others it is simply an afterthought dot on a nameless road. Driving along that road yourself you pass a sign that proclaims “Senter”, but see very little that seems to legitimize ... More »
