## Narrative

As the night shift crew was exiting via the decline, they encountered a slough of ground from one rib 22'W x 12'D x 10'H. The toe of the sloughed material angled to the sill of the opposite rib. The crew decided not to drive their tractor any further and walked out 550' to portal. Ground was past some anchors.
