Article on Diamond Drilling on the Mesabi


  1. Why do you think it was important to Longyear's success that he had the first diamond drill in the area?

  2. Where might we go to look for more information about how a diamond drill worked?

  3. How might this article help us find the buildings where Longyear's offices were located?
