 News of a mine operating under sections of Gordon Moore Park in Alton caught some people by surprise this week. How long has mining been going on in the area? The former Alton Township supervisor and local historian says it's thought mining along the bluffs and other nearby areas actually began more than 150 years ago before the city was platted. And Saturday night is the Brighton Independence Day at the park celebration. There'll be activity starting at 8 a.m. with a fishing derby and casting contest. We'll have fireworks that evening over Schneider Park.
