Roof Fall occurred 2nd West, #2Entry @ Intersection of XC #35 (Outby area). Appears 20' x 20' & 7' high. No one was injured or entrapped and no Ventilation was interrupted. The diagnoses are that the Intersection was wide, (67' sum of the diagonals), and water dripping from a test hole saturated the upper Mud Stone strata, allowing it to fail. New Support has been installed.
