Giant .. the massive triangular plateau in Egypt is three times bigger than the Great Pyramid at Giza
Angela Micol spent 10 years surveying the Nile river basin and has now pinpointed two sites 90 miles apart containing distinctively shaped mounds.
One site includes a 620ft-wide triangular
plateau almost THREE TIMES the size of the Great Pyramid at Giza.
If the remains prove to be from a genuine pyramid, it would be the largest ever discovered.
Micol, based in North Carolina, US, is now planning an expedition to confirm what exactly the mystery site is.
She said: “Upon closer examination of the formation, this mound appears to have a very flat top and a curiously symmetrical triangular shape that has been heavily eroded with time.
“The images speak for themselves. It\'s very obvious what the sites may contain.
“But field research is needed to verify they are, in fact, pyramids.”
All the known pyramids were constructed around Cairo but the latest sites are much further south.
The first area sits alongside the Nile in Upper Egypt, 12 miles from the city of Abu Sidhum, while the second, 90 miles north, contains a 140ft wide, four-sided shape.
Micol added: \'It has a distinct square centre, which is very unusual for a mound of this size and it almost seems pyramidal when seen from above.”
There are also three smaller mounds “similar to the diagonal alignment of the Giza Plateau pyramids.”
Micol has used Google Earth before to discover a potential underwater city off the Yucatan peninsula in Mexico.
American Egyptologist Dr Sarah Parcak also identified 17 lost pyramids thanks to Google Earth in May last year.
