This stock photo includes the Calgary Tower and several reflective modern geometric commercial high-rise buildings in the city of Calgary, Alberta, Canada. Economic activity in Calgary is mostly centered on the petroleum industry however agriculture, tourism, and high-tech industries also contribute to the city's economic growth. The tall modern geometrically shaped structures seen here are striped with windows that reflect the coppery hue of the Sun. The lower sky is clear to near the top of the Calgary Tower, but above that the sky is cloudy and dark. Calgary is the largest city in the province of Alberta, Canada. It is located in the south of the province, in an area of foothills and high plains, approximately 80 km (50 mi) east of the front ranges of the Canadian Rockies. Calgary is an important centre of trade and tourism for the western prairies. It is your most likely point of access for Banff and Jasper, and a worthwhile destination in its own right.
