Here is another super dangerous chimney picture. This is the top flue of a chimney that has an old Vermont Castings Defiant stove that was tapped into the flue above the smoke shelf of a fireplace below. Even a hot eight inch flue into this... 12 x 12 interior chimney was able to develop this kind of creosote. A chimney liner installed and properly scheduled sweeps would make this a much less dangerous setup. (Example of clean flue on the second picture).
