One my student produced a 12 minute video of the 2013 archaeology field school I directed, which focuses on excavation of an early 20th century Japanese logging camp near Vancouver, BC. It is short on talking heads explaining things and results of excavations but it gives a good feel for the nature of archaeological fieldwork and a bit of lab work.
