The answer to one of the mysteries of how the Egyptians built the great pyramid may have been discovered. Archaeologists working in the ancient quarry at Hatnub found a steep ramp with staircases and numerous post holes along side of it. They are specualting that a massive stone block could have been moved by placing it on a wooden sled and then using ropes attached to the sled and the posts lining the ramp. This would hve been much easier than the method of having massive numbers of men pulling the block up a steep ramp manually using only ropes to haul it.
Apparently two inscriptions of Kufu's were found near the ramp, which would indiate that this system of moving large stone blocks was known at the time of the building of the great pyramid.
