An illlustrated introduction to the Susquehanna-Shale Hills Critical Zone Observatory!
By Justin Richardson and Jennifer Z Williams.

From left to right: Tim White, Lixin Jin, Jennifer Williams, Henry Lin, Sue Brantley, David Eisenstat, and Tess Russo. These are just some of the wonderful scientists who have led research at Shale Hills CZO.
Panel 1. A view of the ridge and valley landscape found at the Susquehanna-Shale Hills Critical Zone Observatory (SSHCZO).
Panel 2. Dr. Sue Brantley stands in a catchment, waves and says, “Hi, I am Dr. Sue Brantley and I lead the research conducted at the SSHCZO.”
Panel 3. A cross-section of the ground at the SSHCZO in Pennsylvania shows a temperate forest on sedimentary rock.
Panel 4. Sedimentary rocks here were deposited in a shallow ocean environment ~430 million years ago and uplifted ~300 million years ago to form the hills and valleys seen today.
Panel 5. Ironworkers work in the foreground as downed tree logs lay across the landscape. The region was logged for charcoal to support the local iron industry.
Panel 6. A sign for the Shaver’s Creek Environmental Center, a local education center, is shown. The SSHCZO region is now used for recreation and education.
Panel 7. Dr. Brantley looks at a map of instrumentation in the SSHCZO and says, “One of our main goals is to determine how the CZ will look and function in the future using observations made today.”
Panel 8. The instrumentation helps researchers understand how bedrock affects soil, water, and nutrients for plants and humans. A turtle and couple of rabbits sit by a tree with roots down into a soil profile.
Panel 9. The Shale Hills watershed has a comprehensive set of instruments to measure water, energy, elements and other geochemical conditions including soil lysimeters, wells, and a flux tower.
Panel 10. CZ researchers stand at the entrance to the SSHCZO catchment. Dr. Brantley says, “Understanding how the CZ works is important for sustainability and protecting our natural resources.”
