Oliver started an iron industry in Pittsburgh,Pennsylvania.He found his iron ore in northern Minnesota.Also everyone that invested into this industry had to be wealthy because it was an expensive.
Yay the train is here so we can load the iron.
The iron industry was based in North-Eastern Minnesota.They chose this place because its by a railroad which ships the iron ore too ships on lake superior which it makes it really easy to ship.
This cell is about natural resources one of the ways they got natural resources is they found a hill filled with iron ore called Mesabi hill.It was also pretty expensive to invest into.
Look at the new materials that came in today.
They started with steam powered shovels and steam powered trains to haul and get the iron.As time passed the trains changed to diesel trains and the shovels changed too electric shovels.That cell was about the machines.
This cell is about the people.Although the investments into iron mining are very important,the people are so important.They have thousands of workers basically all the labor are from people working.
All the industries including the iron industry grew their economy through the 1900's.They kept getting better and better at helping the economy because of how many new machines and materials they had.
