A subsidence that opened Friday has closed a road near Shamokin.
DEP said Monday officials are looking at old mining records to determine if the hole that opened on Northwestern Academy Drive is due to an old mine.
A smalls section of the road is closed forcing workers at Northwestern Academy and Reinhart Food Service to take a detour until the subsidence is filled.
DEP said the hole is 35 feet deep and 25 feet wide. It is near a small bridge off Route 61 in Coal Township.
According to DEP, they have to know what caused the hole before it can be filled.
