What were Spanish, British, Russian, and American explorers looking for when they voyaged to North America? They were looking for several things. According to Dale A. Lambert, one of them was more land to expand their territory. The more land you own the better, right? "They came to acquire land and establish new colonies," said Lambert. Another reason other countries explored North America is because they wanted to claim the land for riches. "Explorers came in search of gold, silver, and furs," Lambert said. Last, some explorers came to North America to find the Northwest Passage. According to Dale A. Lambert, "They sought adventure, exploration, and the Northwest Passage."
