Backfill Stability <br />There are no unstable areas in the reclaimed Meadows Mine area. <br />2. Wiring and Seep Survey <br />The landslide area at the old crusher site has at least three active seeps. <br />There was not enough moisture to measure. There are two wet spots on <br />the west facing reclaim. <br />3. Underground Mine Subsidence <br />An area 120' x 12' x 3'-5' deep has caved some 500 plus feet south of the <br />northwest sediment trap. It appears to be a north-south entry or room <br />approximately 120 plus feet below the surface. Sun Coal has fenced the <br />cave-in from the old Routt Pinnacle mine. The old mine bench and entries <br />are below the haul road near Eilts' oil tank. <br />4. H dv rology Monitoring Data <br />Water samples were taken March 26, 1993 and October 20, 1993 <br />5. Reve etg anon <br />The vegetation was again monitored by Agricola in July, 1993 and a report <br />mailed to you. <br />
