Fire History

Geochronology is a discipline of geoscience which measures the age of earth materials and provides the temporal framework in which other geoscience data can be interpreted in the context of Earth history. This knowledge helps to answer questions such as when did a volcano last erupt, what is the rate of crustal uplift in a specific area, are rocks at one gold prospect the same age as those at another.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

This is a landscape level GIS coverage of large fires within the Yukon, spanning a period from 1946 to present. Original polygon size was limited to 200 hectares, when the first edition of this dataset was completed in 1997. Smaller fires are now being included, especially near communities. It is important to note that in most instances, fire perimeters only were mapped. This means that unburned areas within the perimeter are not accounted for, either in an ecological context or in annual area burned summaries. More recent fires mapped, with the aid of satellite technology may include large unburned patches.Although the temporal scale of the coverage goes back to late 1940's, Yukon-wide fire detection capability was not fully developed until the 1960's. In addition to this, access to regular aerial mapping was not readily available until that same time period. As a result many fires in the 40's and 50's were simply not recorded or poorly mapped, particularly in the north. For that reason, care must be taken when drawing conclusions from these data as it relates to the early years.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Holds historical data for mineral and placer, claims and leases, as well as, coal license applications, licenses and leases within the Province of British Columbia. This layer is utilized by Mineral Titles Online title history on the mineral, placer and coal viewers, respectively.

Historic placer mining areas in Yukon can be grouped into ten areas: Klondike; Sixtymile; Fortymile; Clear Creek; Moosehorn Range; Stewart River; Whitehorse South; Mayo; Dawson Range and Livingstone Creek. Each area has its own geomorphic setting and depositional history which is related to its glacial history. Several Quaternary glacial advances have been described in Yukon, and these are generally divided into three episodes, commonly known as the pre-Reid, Reid and McConnell, in order of oldest to most recent.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

This dataset is a collaborative project by Natural Resources Canada and the federal, provincial and territorial members of the Geographical Names Board of Canada, illustrating a curated selection of official geographical names in Canada that have changed over time. The selection comes from the Canadian Geographical Names Database, displaying additional information including the previous name(s) of each feature, the year and the reason why the names changed along with a short history of each name change.

Historic view of areas within the province of British Columbia where mineral, placer and coal titles were once restricted and placer titles are permitted. This business view contains a detailed set of attributes.

644 datasets of hourly meteorological data for all of Canada from various periods (1998 to 2020). The values of the records for solar irradiance are primarily based on satellite-derived solar estimates. This dataset has been updated with the most recent changes made in March 2023. The solar values in these files are based on 0.1° x 0.1° (11 km x 11 km grid) for all of Canada.
