Final "Orange" Series Photos

The entrance of the Church Hill Tunnel was shown in my last post. The site also has extensive contamination. The orange color seen here is caused by the oxidation of metal pollutants.

The orange also creeps down the front face of the tunnel entrance. The byproduct of the oxidation reaction is probably highly acidic. This likely has greatly eroded the remains behind this wall….

A dumpster outside of the abandoned building from Jackson Ward also appears to contain similar contaminants.
