Southern Yukon's Dorsey Lake area features bedrock geology mapped at a 1:50,000 scale. The layered rocks originated as continental shelf sediments overlain by volcanic arc successions, now forming the Yukon-Tanana terrane. The map was published by the Government of Yukon and last updated on April 17, 2026.
Neoproterozoic to lower Paleozoic strata from the western Laurentian margin are preserved in the northern Cordillera. The Government of Yukon provides geochemical and geochronological data for late Cambrian and Late Ordovician mafic igneous rocks concentrated along the Dawson fault in central Yukon. Data includes U-Pb zircon dates and fossil ages from interbedded strata.
TES/Aura Level 2 Ancillary Special Observation Product Version 8 contains retrieved atmospheric profiles from the Tropospheric Emission Spectrometer instrument, which operated aboard NASA's Aura satellite from its launch on July 15, 2004. The dataset provides species volume mixing ratios, temperature profiles, surface temperature, and associated error estimates derived by comparing observed spectra to modeled spectra via radiative transfer algorithms. Each global survey consists of observations from up to 16 consecutive orbits, with the retrieval methodology changing on April 24, 2005, from two to three low-resolution scans per nadir sequence.
Government of Yukon geological mapping data covers map sheets 116A/10 and 11 in the eastern Ogilvie Mountains. The dataset likely contains information on sedimentary, volcanic, and intrusive rocks ranging from Early Proterozoic to Triassic age. It was last updated on 2026-04-17.
A 2004 pilot study produced this biophysical map of the Watson Lake area (NTS 105A/2) in Yukon. The map describes terrain conditions and ecological values at a 1:50,000 scale. It was created by the Government of Yukon as an essential tool for stewardship and sustainable development.
Government of Yukon research describes the four-phase McConnell glaciation history of the Big Salmon Range in the Pelly Mountains. The record includes phases of local alpine glacier advance, Cordilleran ice sheet overtopping, meltwater ponding and erosion, and a late-glacial readvance. The dataset was last updated on April 17, 2026.
From 17 March to 16 May 2016, bathymetry data was collected over the Lord Howe Rise plateau by Geoscience Australia and JAMSTEC. The survey covered 62,360 km² at water depths of 1000-3000m, producing eight bathymetry grids with 50 to 80m resolution. This data supports site assessment for a potential deep stratigraphic drilling project proposed to the International Ocean Discovery Program.
Central Yukon's Tintina Trench exposes bimodal Tertiary volcanic rocks in the Glenlyon, Grew Creek, and Ketza areas. Basalt and rhyolite are interbedded with coarse sedimentary rocks, preserved in grabens, and form various deposits and intrusions. The dataset is provided by the Government of Yukon and was last updated on April 17, 2026.
206,344 cubic meters of material were deposited by a high-magnitude debris flow in July-August 2000 in southwest Yukon. The event, with a peak discharge on the order of 1000 cubic meters per second, is the largest reported in the St. Elias Mountains in the last 100 years. The dataset was published by the Government of Yukon and includes tree-ring analysis and precipitation records.
Yukon hosts a group of hydrothermal breccias known as Wernecke breccia, formed at approximately 1.60 Ga. This paper describes a volcano-sedimentary succession interpreted as a megaclast within the breccia, adding detail to a postulated Proterozoic terrane. The dataset is a text document from the Government of Yukon, last updated in April 2026.
A geological dataset from the Nadaleen Range in Yukon describes pentlandite-bearing serpentinized ultramafic flows with komatiitic composition. It is associated with listwaenites carrying gold, copper, nickel, and cobalt values, representing a new exploration target style. The dataset was published by the Government of Yukon and last updated on April 17, 2026.
Bedrock mapping data highlights two exceptionally well preserved, undeformed and unmetamorphosed volcanosedimentary sequences of Late Paleozoic age in the southern Semenof Hills, central Yukon. The sequences include fragmental volcanic rocks, basaltic lava flows, volcanic conglomerate, and fossiliferous Upper Carboniferous limestone. The dataset is provided by the Government of Yukon and was last updated in April 2026.
Central Yukon bedrock mapping results from the Glenlyon and northeast Carmacks areas. The dataset likely contains geological information on metasedimentary, metavolcanic, and plutonic rocks of the Yukon-Tanana Terrane, including Carboniferous arc volcanic rocks and Early Jurassic and Cretaceous plutons. It was published by the Government of Yukon and last updated in April 2026.
Roadside Geology of the Dempster Highway, Northwest Territories & Yukon is a geological roadmap for Canada's most northern highway. The dataset likely contains geological information along the 717.5 km route from Dawson City, Yukon, to Inuvik, crossing the Arctic Circle and traversing the Ogilvie and Richardson mountain ranges. It was published by the Government of Yukon and last updated on April 17, 2026.
The Atlantic Ocean between southern Africa and South America was the focus of the TRACE-A campaign from September 21 to October 24, 1992. This dataset combines in-situ trace gas measurements from instruments onboard a NASA DC-8 aircraft with supplementary satellite data from NOAA and TOMS instruments. Its primary objective was to determine the cause and source of high tropospheric ozone concentrations observed in the South Atlantic.
From September 21 to October 24, 1992, the TRACE-A mission collected in situ atmospheric data over the Atlantic Ocean using a NASA DC-8 aircraft equipped with 19 instruments. The dataset includes meteorology, navigation, and trace gas measurements from instruments like TP-LIF and DACOM, targeting ozone and other compounds. It was part of NASA's Global Tropospheric Experiment (GTE) to determine the source of high ozone concentrations between southern Africa and South America.
A report summarizing the first use of microscopic tephra analysis methods in northwestern North America. Five peatland sites in southeastern Alaska were cored, yielding 14 significant layers representing at least 4 different tephras. The dataset is provided by the Government of Yukon and was last updated on April 17, 2026.
140 km² of the Eocene Skukum volcanic complex, 60 km south-southwest of Whitehorse, unconformably overlies Cretaceous granitic and Precambrian metasedimentary rocks. The Government of Yukon provides this geological study, which describes an interlayered sedimentary-volcanic sequence and altered felsic pyroclastic flows up to 800 m thick. The formation provides a control on the paleotopography, depositional environment, and provenance of the Skukum area.
Burwash Landing, Yukon earthquake data was analyzed using deep learning and template matching on temporary and permanent seismic station recordings. The study identified 103 local earthquakes, with 28 located in a geothermal resource potential area, and detected 46,432 regional earthquakes over 13 years. The dataset was published by the Government of Yukon and last updated in April 2026.
A 1:50 000 scale biophysical map produced in 2004 for the Watson Lake area in Yukon. The map describes terrain conditions including surficial geology, slope, drainage, and permafrost, as well as ecological values like vegetation community and soil regimes. It was created by the Government of Yukon as part of a pilot project to facilitate stewardship and sustainable development.
