The population of the general area increased enormously and reached 30,000, composed largely of American prospectors. Some realized how difficult the trek ahead would be en route to the gold fields, and chose to stay behind to supply goods and services to miners. Within weeks, stores, saloons, and offices lined the muddy streets of Skagway. The population was estimated at 8,000 residents during the spring of 1898 with approximately 1,000 prospective miners passing through town each week. By June 1898, with a population between 8,000 and 10,000, Skagway was the largest city in Alaska.
