I briefly visited this site back in August 2003, at that time there was next no visitor information on the site. There was a very small museum consiting or a small room with a table with a few boxes on it with stone items in them labeled as axes and knives; and a heap of stone tools lying on the ground outside the door.
The excavation archives and many of the finds are housed at the University of Illinois (USA).
At the time of my visit there was not much to see although improvements were being made to footpaths and signage
