CASSP is the California Archaeological Site Stewardship Program, where trained volunteers work with professional archaeologists to protect archaeological and historical resources by regularly visiting sites and recording changes. CASSP is not a government program; it is organized by the Society for California Archaeology (SCA).
In order to become a CASSP volunteer, you must attend a two-day, training workshop (see how to join). Pre-registration must be made by e-mail, mail, or phone as soon as possible, but no later than the Monday before the workshop (see registration). The volunteer training workshop fee is $25 per person. Attendance usually is limited to 25.
