On Saturdays news there was a report of a " sink hole" which opened up on the 1500 of Mulberry Street in Scranton. Local utilities were going to check the subsidence to see if it was caused by a water main break, or a mine subsidence. It may very well be a subsidence, as there is only 3 feet of wash and 13 feet of rock cover in that area. It was flushed in the 70's ( ASP 12-2) by Empire construction company. This was by the controlled method of flushing ( men in mine directing flush material), and some blind flushing. Some chambers were inaccessable due to roof falls and gob. And those areas were not accessable on the surface to drill boreholes for the blind method. So it is possible the subsidence (?) could be mine related. Tom Supey who was involved with flushing the east side of this area ( ASP 12-1) said in many areas tree roots were growing through the roof, and machinery from factories above could be heard running. That gives you an idea of how close they mined to the surface.
