Leif Erikson
Leif Erikson or Leif Ericson ( 970 – c. 1020) was a Norse explorer from Iceland. He was the first known European to have set foot on continental North America (excluding Greenland), before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, tentatively identified with the Norse L'Anse aux Meadows on the northern tip of Newfoundland in modern-day Canada. Later archaeological evidence suggests that Vinland may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station.
Hispanic and Latino Americans
In 1540, Hernando de Soto undertook an extensive exploration of the present United States. That same year Francisco Vásquez de Coronado led 2,000 Spaniards and Mexican Indians across today's Arizona–Mexico border and traveled as far as central Kansas, close to the exact geographic center of what is now the continental United States. Other Spanish explorers of the US territory include, among others: Lucas Vázquez de Ayllón, Pánfilo de Narváez, Sebastián Vizcaíno, Gaspar de Portolà, Pedro Menéndez de Avilés, Álvar Núñez Cabeza de Vaca, Tristán de Luna y Arellano and Juan de Oñate, and non-Spanish explorers working for the Spanish Crown, such as Juan Rodríguez Cabrillo. In all, Spaniards probed half of today's lower 48 states before the first English colonization effort in 1585 at Roanoke Island off the East Coast.
