Since then, Weeks and his crew have been excavating, preserving, measuring, and documenting the interior, slowly but surely removing the cement-like flood debris that filled a good part of the tomb. No great treasures have been found. They've uncovered damaged wall inscriptions as well as pieces from ushabtis, sarcophagi, canopic jars, and pottery. Some items carry the names of four of the sons of Ramesses II, confirming the use of the tomb for them. The amazing thing about the tomb is its structure and the chambers, which now number 108 and are expected to grow to almost 150.
Weeks believes the tomb was built in four stages.
The entrance chambers and the 16-pillar hall were part of stage one. These probably date to the 18th Dynasty. The rooms around the pillared hall marked stage two. The parallel corridors and rooms that lead from the pillared hall back toward the tomb of Ramesses II formed stage three. The long corridor with the relief of the Osiris figure and corridors off it forming a T were part of stage four.
