Cariboo F fire, 7 July 2017 Cariboo F
Out · last detection 4 Aug 2017, 10:48 UTC
The fire started on 7 July 2017 in Cariboo F, Canada, and satellites saw it burning for 29 days. Canada’s CWFIS (Natural Resources Canada) mapped an official burnt perimeter of 2,831 hectares from satellite imagery, spread across a single census subdivision.
It is the 202th largest in British Columbia since 2016 (of 343 with a page). Number 118 in Canada in 2017, of 242.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

Burnt area inside each census subdivision, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2015Built-up area0.21 ha
Residents< 20
Inside the perimeter there were about 0.21 hectares of built-up land and almost nobody lived there (GHSL 2015, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2018.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Cariboo F fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 7 July 2017 to 4 August 2017 (29 days). The perimeter dates it from 7 July 2017 to 3 August 2017.
- How much area did it burn?
- The official perimeter mapped by Canada’s CWFIS (Natural Resources Canada) is 2,831 hectares (28.3 km²). Other tallies, such as those of provincial agencies, may give slightly different figures.
- Which census subdivisions burned?
- The fire only entered Cariboo F (2,807 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 31.6 °C, humidity dropped to 12 % and gusts hit 55 km/h. The fire danger index (FWI) reached 58, class Extreme.
- Where does this data come from?
- From the official burnt perimeter of Canada’s CWFIS (NBAC, Natural Resources Canada) or, for the current season and until NBAC publishes it, the one rebuilt by GWIS (Copernicus); from NASA FIRMS VIIRS hotspots; and from the administrative boundaries of Canada. It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

- Dates adjusted with the VIIRS detections inside the perimeter, which said 7 July 2017 to 3 August 2017. 764 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2015, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter is official: it comes from the National Burned Area Composite (NBAC) of the Canadian Wildland Fire Information System (CWFIS), Natural Resources Canada, which maps it on satellite imagery and publishes it under the Open Government Licence – Canada. Until NBAC publishes the current season, this year’s fires carry the perimeter rebuilt from heat detections by GWIS (Copernicus, CC BY 4.0), which is approximate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Census subdivision boundaries come from geoBoundaries ADM3 (Open Data Commons Open Database License 1.0). The area per census subdivision is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from official figures.
