The Pyramids of South Dahshur are all from end of 12th dynasty or the first intermediate period. All are also very difficult reach. I was only able to visit the site of Mazghuna, albeit just briefly and at a distance. It is believed by some Egyptologist that the Mazghuna pyramids can be attributed to Amememhet IV and Sobekneferu, the successors of Amememhet III. Although neither of these names have been found d at the sites. The South Mazghuna pyramid is about 4.8 km south of Sneferu's Bent Pyramid. None of the pyramids appear to have been completed.
