Map of the Hudson Bay-Arctic Lowlands

The four major cities are Peawanuch, Fort Severn, Churchill Winisk and Moosonee.

Most of the bedrock in the Hudson Bay-Arctic lowlands is composed of lime stone and carbonate - dominated sedimentary rocks. The Hudson Bay low lands were formed by eroded parts of the Canadian shield that were gradually pushed down into rocks. The weight of the glacier dug up the residue and changed the surface, hence why the Hudson Bay low lands is mostly composed of lime stone.

The surrounding Hudson Bay-Arctic lowlands is a little plane locked and permafrost and characterized by marshes, peat and innumerable ponds. Much of the hydroelectric potential of the area develops at the point where powerful rivers search out of the shield onto the lowlands.

The main economic activities for the Hudson Bay-Arctic lowlands are fishing and tourism. The resources untilisted in this region have historically related back to original aboriginal hunting, trapping and fishing and, will continue to relate in that way. The people of the Hudson Bay-Arctic lowlands also enjoy mineral exploration and mining.

The factors that affect climate change in this region are latitude, ocean currents, winds and air masses and nearness to water. All of these factors slowly warm up this region and causing the Churchhill polar bears their habitat being melted away. There is much less ice cover, warmer water and temperatures in the lake are catastrophically warm being the cause of more small lakes and ponds and less ice land.
