The HBC built a new much larger Fort Vancouver in 1824 slightly upstream of Fort Astoria on the north side of the Columbia River (they were hoping the Columbia would be the future Canada–U.S. border). The fort quickly became the center of activity in the Pacific Northwest. Every year ships would come from London to the Pacific (via Cape Horn) to drop off supplies and trade goods in its trading posts in the Pacific Northwest and pick up the accumulated furs used to pay for these supplies. It was the nexus for the fur trade on the Pacific Coast; its influence reached from the Rocky Mountains to the Hawaiian Islands, and from Russian Alaska into Mexican-controlled California. At its pinnacle in about 1840, Fort Vancouver and its Factor (manager) watched over 34 outposts, 24 ports, 6 ships, and about 600 employees.
