Five clear, rotating disks provide beautiful windows onto the motion of sediments in the Bay. Spin them to compare the behavior of gravel, sand, and fine silt—how the currents carry them and how they settle out of the swirling waters.
A beautiful new location, brand new and beloved exhibits, cool events, and more! Buy your tickets now.
