A year after its incorporation on November 12, 1907, the Lakeside Amusement Park, nicknamed "White City", opened on the eastern shores. Both town and park were founded by a syndicate led by prominent Denver brewer Adolph Zang, who endeavored to build the resort just across the county line from Denver, and incorporate to move beyond the reach of Denver liquor laws.
