Description: Students in a Michigan Tech geophysics field course found a sudden change in surface topography when they came upon a cave-in of a shaft of the old Hancock Mine at White, Shafter and Pine streets in Hancock. Art Ettlinger measures the depth to a ledge, which is 25 feet. The diameter of the gaping hole is about 12 feet. The students have been doing preliminary work in the area, mapping the layout of old underground workings that could possibly lead to furture subsidence, and have been walking on top of the shaft a few days earlier. The shafts' cave-in was blamed on its never having been properly sealed. The city has fenced and posted the hazard until steps are taken to correct it.
