Backfill Stability <br />There are no unstable areas in the reclaimed Meadows Mine area. <br />2. Spring and Seep SurveX <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. Hydrology Monitoring Data <br />Water samples were taken March 16, 1994 and Apri120, 1994 <br />5. Reve etation <br />The vegetation is being monitored by Savage this week and a copy of the <br />report mailed to you. <br />
