and the lower Canal Lift Bridge. (Requires navigation to relevant articles.) Between 1788 and 1793, the townships at the Head-of-the-Lake were surveyed and named. The area was first known as The Head-of-the-Lake for its location at the western end of Lake Ontario. 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." George Hamilton, a settler and local politician, established a town site in the northern portion of Barton Township in 1815. He kept several east–west roads which were originally Indian trails, but the north–south streets were on a regular grid pattern. Streets were designated "East" or "West" if they crossed James Street or Highway 6. Streets were designated "North" or "South" if they crossed King Street or Highway 8. The overall design of the townsite, likely conceived in 1816, was commonplace. George Hamilton employed a grid street pattern used in most towns in

and throughout the American frontier. The eighty original lots had frontages of fifty feet; each lot faced a broad street and backed onto a twelve-foot lane. It took at least a decade for all of the original lots to be sold, but the construction of the Burlington Canal in 1823, and a new court-house in 1827 encouraged Hamilton to add more blocks around 1828–9. At this time, he included a market square in an effort to draw commercial activity onto his lands, but the natural growth of the town was to the north of Hamilton's plot. The

called the Beachstrip. The first aboriginals to settle in the Hamilton area called this bay ''Macassa'', meaning ''"beautiful waters"''. This sandbar was deposited during a period of higher lake levels during the last ice age, and extends southeast through the central lower city to the escarpment. Hamilton's deep sea port is accessed by ship canal through the beach strip into the harbour and is traversed by two bridges, the QEW's Burlington Bay - James N. Allan Skyway and the lower Canal Lift Bridge. Hamilton Harbour ranks one of Canada's largest seaports. The ''Hamilton Port Authority'' manages the heavily industrial harbour.

Some 'sections' of the city include: Ainslie Wood, The North End, Downtown, the East and West End, Westdale (the area where McMaster University is located, and therefore has a high percentage of students), Beasley, Crown Point, McQuesten, Stinson, Locke, Dundas, Ancaster (including Meadowlands, which is often seen as separate from Ancaster), the West, Central, and East Mountain, Stoney Creek and Stoney Creek Mountain. These areas are all unique, and the people, economy and cultures vary a great deal across the city.

Parks

Acting on provisions of the Public Parks Act of 1883, the voters of Hamilton, on 8 January 1900, endorsed a by-law establishing the Board of Parks Management, an independent body whose members were appointed for three-year terms. The need for the new organization was obvious as when it began there were only three formal parklands at the disposal of residents in the community; ''the Gore'', acquired by the city in 1852, ''Dundurn'', which was appropriated by the City in 1899, and ''Victoria Park'' on King Street West, which by this time had lost an imposing landmark, the Crystal Palace. From then on other parks were opened in town because of the efforts of the group. These include, (in

Climate

The climate of Hamilton is humid continental (''Dfa'' type) and relatively mild compared with most Canadian cities. The average January temperature is downtown, but many days rise just above freezing often making for slushy conditions during snowfalls. Winter snowfall averages with great year-to-year variation.
