Briefly summarized, Bear Coal is <br />requesting permission to cease monitoring many of the older subsidence <br />monuments. The majority of the older monuments were required to verify the <br />stability of the ancient landslides on the slopes of the North Fork of the Gunnison <br />Bluer, opposite the townsite of Somerset, Colorado. During the permitting of the <br />Bear Mine #3, the Diuision expressetl a concern that reactivation of these slides <br />might affect the North Fork. The result of the past eight years of monitoring, <br />attached to the application, demonstrate that while the slopes haUe subsided as <br />predicted, no deleterious rejuuenatlon of the ancient slides has occurred. Bear <br />Coal will not remove these monuments, so they could be resurveyed at the <br />Division's request in the Tuture. <br />Bear Coal will also continue monitoring the three monuments (U25, U26 and 1 <br />recently installed in Lone Pine Gulch.
