Partridge Island

Partridge Island is located in the Bay of Fundy, about 1 km from the shoreline and the city of Saint John, New Brunswick. The island was set aside as a quarantine station in 1785 and operated as such between 1830 and 1941. Many immigrants arriving to Canada by ship, including thousands of  Irish in 1847, were isolated on the island before being allowed to enter the country. This was done in an effort to prevent the spread of infectious diseases common on overcrowded vessels. In 1974, the Partridge Island quarantine station was designated a national historic site. Other important events are associated with the island, including the installation of the world’s first steam-operated fog alarm in 1859 (see also Robert Foulis).

Meteors, Meteorites and Impact Craters

The solar system contains many objects smaller than the planets (or their satellites) travelling in individual orbits about the SUN; space between the planets also contains myriad dust grains in the micron size range. Near Earth, dust concentrations are only a few hundred particles per cubic kilometre, but 35 000 to 100 000 t of extraterrestrial material enters the atmosphere annually, swept up by our planet from debris that is in its path or crosses its path.

Fraser River Lowland

The Fraser River Lowland is a triangular area in southwestern British Columbia. The eastern apex of the triangle is at Hope, about 160 km inland from the Strait of Georgia. From here, the lowland broadens to the west to a width of about 50 km. The international boundary between British Columbia and Washington State crosses the southwestern part of the lowland. The Coast Mountains form the northern boundary of the delta-lowland. The Fraser River Lowland is the largest area of level land with suitable agricultural soils in coastal British Columbia.

Trails and Greenways in Canada

Canada was founded along the many waterways utilized by Indigenous peoples, early explorers, fur traders and pioneers. As Canada became a more developed nation, the automobile and roads began to dominate the landscape. Trails were almost forgotten, except in parks and other protected areas. Today, however, Canadians are using trails in increasing numbers. Trails are either managed by organizations such as parks, municipalities and First Nations, or unmanaged. As of 2010, there were 278,576 km of managed trails in Canada. This distance is roughly the equivalent of traversing the country, from Cape Spear, Newfoundland and Labrador, to the Yukon-Alaska border, 50 times. The province with the largest managed trail network is Quebec. Just over 27 per cent of all managed Canadian trails (77,030 km) are found there.
