The only technology that can 'see' beneath the ground is radar imagery. But satellite imagery also allows scientists to map short- and long-term changes to the Earth's surface. Buried archaeological remains affect the overlying vegetation, soils and even water in different ways, depending on the landscapes you're examining.

What if Hiram Bingham had the technology to find hundreds of other archaeological sites at the same time and create entire 3-D maps of the ancient landscape accurate to within a few inches?

The most exciting part of what I do is understanding the scale of what we don't know. There are just countless archaeological sites all over the world, and one of the most important and best ways of finding them is using digital technology.

About 15,000 years ago, humans colonised America, wiping out in the process about 75% of its large mammals. Numerous other species disappeared from Africa, from Eurasia, and from the myriad islands around their coasts. The archaeological record of country after country tells the same sad story.

My fiction is reviewed by the mainstream press by science fiction periodicals romance magazines small press publications and various other journals including some usually devoted to archaeological and other science material.
