Little has been recorded of Europeans who might have seen or visited the Rocky Mountain National Park area before the 19th century. French fur trappers visited in 1700s and gave Native Americans firearms in trades. A couple of French trappers called Longs Peak and Mount Meeker Les Deux Oreilles (two ears) in 1799. Don Pedro de Villasur led a group of one hundred men from New Spain up the South Platte River into Nebraska and may have seen the Front Range of Colorado. The Spaniards were attacked by unfriendly Pawnees, who killed 88 of the men, and the Spanish lost interest in traveling so far north again.
