Archeology: Start to Finish

  1. 1. Start to Finish
  2. 2. PHASE I ARCHAEOLOGY <ul><li>IS THERE A SITE IN THE PROJECT AREA? </li></ul><ul><li>The most common way to find out is through shovel tests excavated every 50 to 100 feet in undisturbed areas. </li></ul>
  3. 3. We’ve found an archaeological site with artifacts! Is the site significant?
  4. 4. GEOMORPHOLOGY <ul><li>GEOMORPHOLOGIC SURVEY </li></ul><ul><li>Archeological sites along rivers and streams may be deeply buried. The project geomorphologist examines soils to determine the potential for buried sites. </li></ul>
  5. 5. PHASE II ARCHAEOLOGICAL TESTING <ul><li>Excavation of Phase II units to find more information </li></ul>
  6. 6. URBAN ARCHAEOLOGY: TESTING IN THE CITY <ul><li>Pittsburgh’s archaeological sites are buried beneath many feet of urban fill. To penetrate these fills, mechanical equipment is essential. Our skilled operator has over 10 years of experience working with CDC and is a significant member of our team. </li></ul><ul><li>CDC uses a backhoe to begin archaeological testing in an urban parking lot. The goal is to discover if an archaeological site is buried beneath the parking lot. </li></ul>
  7. 7. REPAIRING A LANDOWNER’S PROPERTY AFTER TESTING <ul><li>Once archaeological testing in an urban parking lot is complete, landowners need to return to business. </li></ul><ul><li>CDC resurfaces this parking lot to bring the parking spaces back to original condition. </li></ul>
  8. 8. WHAT DO URBAN ARCHAEOLOGIST FIND? <ul><li>This excavation was over 17 feet below street level (that’s as deep as a two-story building is high!). At the bottom of the excavation were Native American artifacts including kernels of Indian corn. </li></ul>
  9. 9. <ul><li>Brick Wells and Privies are buried beneath buildings and tons of demolition rubble. </li></ul>
  10. 10. ARTIFACTS FROM THE CITY
  11. 11. PREPARING ARTIFACTS FOR PRESERVATION
  12. 12. ARCHAEOLOGICAL CONSERVATION OF PERISHABLE MATERIALS THIS FRAGMENT OF A TORTISESHELL IS 140 YEARS OLD. <ul><li>BEFORE CONSERVATION </li></ul><ul><li>AFTER CONSERVATION </li></ul>
