A little more than twenty years after an attempt was made to blast the adit of the Hibernia Mine shut, instead leaving fractured and dangerously loose rock hanging perilously from a cliff overhead, it appears the mine is finally being stabilized. Upon a recent visit to the historic mine tunnel which is driven more than a mile underground, the trench leading up to its mouth has been mostly cleared of fallen boulders and earth erosion. In fact, it has been so thoroughly removed as to reproduce in elevation, the approximate grade of the narrow gauge railroad that once led up to the opening 100 years ago.
Prior to the stabilization, the adit was obscured behind a massive pile of rubble that obscured its aesthetic grandeur. This pile was the cumulative effect of years of boulders that have detached from bedrock that was weakened during the prior incomplete reclamation. Although the adit hardly resembles its trademark look in 1907 featuring a timbered opening with tracks leading in, it is a pleasing compromise and retains a more historically accurate topography by the removal of erosion. This new look helps reinterpret the level path the unique steam powered locomotives took before entering Hibernia mountain. Good work guys!
In addition, an opening has been secured with concrete to allow bats access to an upper level of the mine. Hopefully all of these efforts will help improve bat habitat in the midst of the current WNS crisis.
