In addition to the services commonly provided by archaeologists and historians, Natural Investigations is one of the few firms in the state of California offering Ground Penetrating Radar (GPR) services. This non-invasive method of subsurface data collection is ideal for those projects where excavation is not possible or not desired. The process is more cost-efficient and reliable as a means of gaining essential information than random subsurface testing.
Our Logo

Our company logo "Fossil Fish" is a registered trademark of Natural Investigations Company, Inc. The original artwork "Fossil Fish" was created by Janet Moore in 1993 at Fresno City College. Janet used a printmaking technique called Intaglio. Starting with a copper plate, she engraved the image using an etching needle. Then she rolled brown ink over the plate and then rubbed it off with a cloth, leaving ink only in the incisions in the plate. A damp piece of thick yellow paper was put over the plate and then the plate and paper were run through a printing press, which transferred the ink from the recesses of the plate to the paper.
