American Egyptologist, founder of Ancient Egypt Research Associates, and the standing mainstream counterparty for the whole Giza revisionist strand. He mapped the Great Sphinx in detail in the 1980s, debated Robert Schoch at the American Association for the Advancement of Science in 1992, and published his reply to the water-erosion reading in KMT 5(3) in 1994.

The site as he reads it

His model of the plateau treats the ground east of the temples as a harbour, which puts the Valley Temple and Sphinx Temple on the edge of a working waterfront rather than at the foot of a ceremonial axis alone.

The 2019 radar

In March 2019 he worked with the Glen Dash Foundation and Zahi Hawass on a ground-penetrating radar survey in front of the south-east corner of the Sphinx Temple. The report, “Where the Water Disappears”, appeared in AERAGRAM 25 in 2024: a uniform reflection about a metre down read as quarried levelling blocks, right-angled reflections to about four metres taken for a buried second course rather than a tunnel, and a closing note that only direct observation can confirm it.
