Specialty Geotechnical Contractor DBM was excavating a drilled shaft for the I-5 interchange in Ridgefield, Washington when they dug up something unusual at a depth of 30-ft. At first the WSDOT inspector thought it looked like wood, but then called in a WSDOT archaeologist who took the fragments to University of Washington’s Burke Museum of Natural History and Culture. The tusk is believed to belong to a Columbian Mammoth and date to approximately 13,000 to 15,000 years ago. Story and image from The Columbian.
Remote sensing with 1-m resolution infrared satellite imagery has allowed US Egyptologist Dr Sarah Parcak to discover a multitude of new archeological sites in Egypt. Her work was the subject of a BBC documentary where […]
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.

An excavator mounted drill rig drilling shafts as part of a project to pass utilities under I-35 near 51st Street toppled over while trying to move in soft, rain soaked soil. The Austin Fire Department was able to extract the operator from the cab and he was taken to a local hospital with minor injuries, a minor miracle. I’m not sure what the purpose of the drilled shafts were for. Since the project was for some kind of utility pipe jacking under the freeway, I’m speculating it was drilling holes for temporary shoring for the jacking pit or something along those lines. I’m sure OSHA will be looking into the incident. Video news story after the break. (Photo from Austin KXAN.com).
