Incorrectly regarded as goofs: There are many historical inaccuracies in this story of Pocahontas, however this is (obviously) a highly fictionalized account of her life.
Factual errors: Indians didn't plant corn in rows.
Continuity: At the beginning of the storm the Union Flag is torn by the storm. Later in the scene, the flag is restored.
Factual errors: Pocahontas follows a compass to the north, while the sun is rising. Her shadow is to her right, when it should be to her left.
Errors in geography: Meeko the raccoon hides atop a moose. There are no moose in Virginia, or anywhere in the warm areas of North America.
Errors in geography: There are many cliffs visible near Jamestown. The land in Virginia near Jamestown is flat.
Errors in geography: Ratcliffe's maps show the island of Hispaniola (today divided between Haiti and the Dominican Republic) underneath Florida, where Cuba should be. Although 17th Century maps are known to be inaccurate, a mistake this obvious is unlikely given that the Caribbean area was well charted by then.
Anachronisms: In some scenes the Union Flag of Great Britain and Ireland is displayed, although this flag was not created until 1801 (nearly 200 years after the movie is set). In other scenes, the St Patrick's cross is omitted.
Continuity: John Smith's helmet disappears and reappears throughout the movie.
Revealing mistakes: When the Native Americans are preparing for the battle, they are surrounding a big fire. Before they move to start the battle, they are all walking towards the center of the circle. As they do this everyone's shadow is right in front of them, as if the sun was behind all of them. This isn't possible since at least half of their shadows would be behind them and not in front of them.
