| Carved out of an ancient floodplain, the small terrace upon which Chetwynd is situated lies in the northern foothills of the Rocky Mountains. Once used as a grazing spot by nomadic Aboriginals, the terrace was farmed by settlers until it was developed into a town. Two types of soil—namely, the Widmark and Centurion Series—comprise the terrace's surface. The Widmark Series—a moderately well-drained degraded loamy, woody, silty, and clay-like soil—lies north of Highway 97. Meanwhile, the Centurion Series—which lies south of the highway—is a poorly drained soil with a dark-brown peaty surface material consisting of decomposed leaves and mosses. These soils, also limited by topography and stoniness, are generally used for forage and pasture.[12][13] The town is surrounded by forested hills but the prairies of the Peace River Country begin here and continue eastward into Alberta. It lies in a transition area dividing two biogeoclimatic regions: the Boreal White and Black Spruce zone and the Engelmann Spruce-Subalpine Fir zone.[14][15] The area's native tree species include deciduous balsam poplar and coniferous spruce and pine. Many fur-bearing animals—deer, moose, elk, beaver, and bear—comprise the region's mammalian wildlife. Three creeks run south through town. Windrem Creek—which flows down from Ol' Baldy Mountain—and Widmark Creek both flow into Centurion Creek, which itself drains south into the Pine River. Weather[16] Time Temperature Precipitation January −10.7 °C (12.7 °F) 28 cm (11.0 in) July 15.3 °C (59.5 °F) 79 mm (3.11 in) Average annual precipitation – 170 cm (66.9 in) The town experiences a cool continental climate, including frigid winters and warm summers. Southwesterly winds, coming off Williston Lake, predominate, with wind speeds averaging around 8.2 km/h (5.1 mph).[17] About 318 millimetres (12.5 in) of rain and 169 centimetres (67 in) of snow fall on the town annually and about 30 days with some fog are expected per year.[17] Chetwynd, like the rest of the Peace River Regional District, uses Mountain Standard Time year-round. The remainder of the province uses Pacific Standard Time with daylight saving time, meaning that Chetwynd shares the same time with the province during the summer and is one hour ahead during the winter.[18] credit union loans vs bank loanspatio chairs | |
