Forty-five years after its June 1981 release, “Raiders of the Lost Ark” is a cinematic treasure sealed in amber. Although she has never been chased by a boulder and doesn’t carry a bullwhip, UCLA archaeology professor Lara Fabian is a real-life version of the main character, Indiana Jones. “I didn’t see it until I was in grad school, already on the path to becoming an archaeologist,” Fabian said. “This is a myth about archaeologists: That we want to find shiny gold things. A garbage pit is way better than a shiny gold bowl, because I can find out from a garbage pit what people were eating, what they were throwing away, what their households looked like.”
