Mysterious, pyramid-like structures spotted in the Egyptian desert by an amateur satellite archaeologist Angela Micol might be long-lost pyramids after all, according to a new investigation into the enigmatic mounds.

Angela Micol, who last year found the structures using Google Earth 5,000 miles away in North Carolina, says puzzling features have been uncovered during a preliminary ground proofing expedition, revealing cavities and shafts.

First reported by Discovery News, her claim gained widespread media attention and much criticism. Authoritative geologists and geo-archaeologists were largely skeptical and dismissed what Micol called "Google Earth anomalies" as windswept natural rock formations -- buttes quite common in the Egyptian desert.

Micol launched Google Earth Anomalies in the early 2000's and Google Earth Anomalies, an active Facebook page.
