Scientists and historians working at Oaklawn Cemetery started using a coring truck Monday to help in the test excavation work in the search for possible mass graves from the 1921 Tulsa Race Massacre.
Archaeologists said the equipment helps them assess soil more quickly than with a backhoe.
They brought up several samples from the ground Monday. Then the team used tools to loosen the dirt off the equipment so they can study it.
Over the weekend, the City of Tulsa shared pictures on its Facebook page, showing some of the artifacts. There are several bottles, pieces of bricks and other items.
News On 6 expects to learn more Tuesday about what the team is noticing about the soil they sampled.
