In 1784, thousands of United Empire Loyalists settled in Upper Canada (what is now southern Ontario). Iroquois loyal to Britain arrived from the United States and were settled on reserves. Between 1788 and 1793, the townships at the Head-of-the-Lake were surveyed and named. John Ryckman, born in Barton township (where present day downtown Hamilton is), described the area in 1803 as he remembered it: "The city in 1803 was all forest. The shores of the bay were difficult to reach or see because they were hidden by a thick, almost impenetrable mass of trees and undergrowth... Bears ate pigs, so settlers warred on bears. Wolves gobbled sheep and geese, so they hunted and trapped wolves. They also held organized raids on rattlesnakes on the mountainside. There was plenty of game. Many a time have I seen a deer jump the fence into my back yard, and there were millions of pigeons which we clubbed as they flew low." Hamilton, the centre of a densely populated and industrialized region, is located in Southern Ontario on the western part of Lake Ontario. Hamilton Harbour marks the northern limit of the city, and the Niagara Escarpment runs through the middle of the city bisecting the city into "upper" and "lower" parts. There are over one hundred waterfalls and cascades within the city, most of which are on or near the Bruce Trail as it winds through the Niagara Escarpment. Two steel manufacturing companies, Stelco and Dofasco, were formed in 1910 and 1912, and Procter & Gamble opened a manufacturing plant in 1914. The Pigott Building was the city's first high-rise building constructed in 1929. McMaster University moved from Toronto to Hamilton, an airport was built in 1940, a Studebaker assembly line started in 1948, the Burlington Bay Skyway Bridge was built in 1958, and the first Tim Horton's store opened in 1964.
