Operational Baseline Information Collection initiated on 12202000 and not yet considered complete after monhodng far-12 months. Point AW-13 has not been influenced by mining. .Alluvial Wells AW-11 through AW-13 are located along the north side of Union Pacific Railroad. They were installed in 200010 develop baseline data for a new train loadout. This Well, AW-13 was inadvertantty destroyed during the construction of the loadout in February 2002.
