A 20-acre abandoned mine site located near two popular recreation areas contained dangerous highwalls and a large, water-filled pit. The site not only posed a hazard to the public, but also raised liability concerns for private landowners who used the property as horse pasture and a hunting area. North Dakota's AML program addressed these issues by eliminating approximately 1,300 feet of dangerous highwalls, creating a pond that recharges fresh water, and preserving a prehistoric, petrified tree stump, estimated to be between 55 and 60 million years old.
