LIDAR Helps Locate New England Archaeological Sites
One of the advantages of LIDAR topography data is the ability to “see through” vegetation so to speak. The light beams aren’t actually seeing through physical objects, but because of the high density of LIDAR […]

Drilling for Origins of Humanity
Lake Malawi is an African rift lake, formed as the earth’s crust is slowly spreading apart. This lake is one of the deepest in the world and one of the lead geologists, Dr. Andy Cohen of the University of Arizona (go Cats!) says that the lake "acts like a rain gauge" and through their drilling expedition they have determined that the lake at one time dropped nearly 2,000 ft between 135,000 and 90,000 years ago. This drought in what is now a lush tropical part of Africa may explain why Man’s early ancestors migrated from that continent. More after the break.

Columbus Era Aztec Emperor’s Tomb Found with GPR
Archaeologists beleive that they may have found the tomb of Aztec emperor Ahuizotl (ah-WEE-zoh-tuhl). Using ground-penetrating radar, they have detected underground chambers that could contain the remains of Ahuizotl, who ruled the Aztecs when Columbus landed in the New World.
This find would not have been possible were it not for strong earthquake in 1985 that severely damaged a Colonial Spanish building. Buildings of this type were built a top the Aztec ruins and are considered too valuable to remove for excavations. Apparently, before this find, no Aztec emperor’s tomb had ever been found at this location despite writings describing an Aztec ceremonial center because Spanish conquerors constructed over the site.
