I have a test where I am given the following article, what is an answer for the question: What is the animal tracker attempting to film when he captures images of Sasquatch? ?  Animal tracker Ivan Marx opens by mentioning the film is the culmination of 10 years of research. He says that the Eskimos called the creature "bushman," the Colville Indians "Sasquatch," and the Hoopas "Om-mah," but is most commonly known as Bigfoot. Marx's brother-in-law takes him to the land of petrified wood, showing him rock carvings of creatures with big hands and feet. The carvings tell the story of the creature stealing children, causing a village to be abandoned. Marx finds large tracks in the snow and later a dead bear with similar tracks nearby. He finds strange hair between the bear's teeth and sets out to track the creature. He finds tracks in the mud beside a river and something moving nearby. He intends to inform others but rain washes the tracks away. Marx investigates tracks in several states only to find they're not bigfoot tracks. He visits the Oh-mah bigfoot redwood statue in northern California and the Oregon coast, continuing to search. Marx takes a job in Washington state to film a Cinnamon bear. While there, he films Bigfoot walking through a field. He mentions that his footage of Bigfoot has been questioned by science and used by others on lecture circuits to make money. Marx shows footage of an injured squirrel, goats eating dirt, and glaciers melting. He mentions the Trans-Alaska Pipeline and visits Yukon Frida, who paints pictures of Bigfoot. Marx travels above the Arctic circle, showing footage of the Northern lights while relating Bigfoot tales. He visits an Eskimo who promises he'll see Bigfoot. Later in the evening, he films what he describes "the shining eyes" of the creature, but when dawn comes, he says Bigfoot disappeared behind a rainbow. Marx shows footage of salmon spawning, geese migrating, caribou, and Alaska moose defending their territory. He searches from a plane and films a young Bigfoot near a river. He lands, but Bigfoot runs away.
