    “Permafrost soils are particularly vulnerable to climate change. To assess and improve estimations of carbon (C) and nitrogen (N) budgets it is necessary to accurately map soil carbon and nitrogen in the permafrost region. In particular, soil organic carbon (SOC) stocks have been predicted and mapped by many studies from local to pan-Arctic scales. Several studies have been carried out at the Canadian Beaufort Sea coast, though no regional maps of terrestrial carbon stocks based on spatial modelling has been conducted yet. This study combines available field data from the Canadian Yukon coastal plain and uses it to map regional SOC and N stocks using the machine learning algorithm random forest and environmental variables based on remote sensing data. [The authors] developed models using the data for the entire region and separate models for the coastal mainland area and Qikiqtaruk Herschel Island. Each model was used to map SOC and N stocks for its respective area. [They] assessed the performance of the different random forest models by using crossvalidation. [They] further assessed model results using the Area of Applicability (AOA) method and the quantile regression forest approach, comparing the results and discussing their implications within the context of both methods. [They] explore[d] local differences in soil properties and how soil data distribution across the region affects the accuracy of the predictions of SOC and N stocks..."

  2. NO ORDINARY RISKS: THREE JOURNEYS NORTH TO THE ARCTIC SEA
    James Green Stewart was clerk to Robert Campbell at Fort Selkirk, on the #Yukon River, and he made some impressive winter journeys while he was there. A few years later he was assigned the position of second-in-command to James Anderson, who was a much more difficult leader to please. #Journeys #ThreeJourneysNorth #NoOrdinaryRisks #NWT nancymargueriteanderson.com/ja

    Public bat banding near Whitehorse shines light on seldom seen Yukon species

    Bats provide the night shift. They’re the ones out there eating mosquitoes, [and] moths and things of that nature. So, without bats, we wouldn’t have control or regulation of some of the nightly flying insects.”

  4. Yukon's Permanent Daylight Time! ☀️⏰

    Yukon made a unique decision in 2020: it permanently switched to what is effectively Pacific Daylight Time, meaning it stays at UTC-7 year-round. No more changing clocks! This aligns it with Mountain Standard Time, offering consistent daylight hours and simplifying life for residents. #Canada #TimeZones #Yukon #NoDST

  5. Nice skies they have up there. And leeches. (Not pictured) #yukon #leeches

    Once he and his men reached the junction of the Porcupine River with the #Yukon, they made their way up the Porcupine to Lapierre House, on the West side of the Richardson Range. #NoOrdinaryRisks #ThreeJourneysNorth #Journeys nancymargueriteanderson.com/po

    Pierre Pambrun Jr worked in the Mackenzie's River district and was attached to Robert Campbell's expedition and post at Frances Lake, and later at the Pelly Banks Post, on the Pelly River in the #Yukon. #Journeys #ThreeJourneysNorth #NoOrdinaryRisks nancymargueriteanderson.com/pi

  8. NO ORDINARY RISKS: THREE JOURNEYS NORTH TO THE ARCTIC SEA
    In 1851, Robert Campbell of Fort Selkirk, on the #Yukon River, built a York Boat and travelled down the Yukon River on his way to the Porcupine. At the junction of the Porcupine with the Yukon, he stumbled on Alexander Hunter Murray post of Fort Yukon. #ThreeJourneysNorth #NoOrdinaryRisks #Journeys nancymargueriteanderson.com/yu

  9. NO ORDINARY RISKS: THREE JOURNEYS NORTH TO THE ARCTIC SEA
    In 1847, HBC trader Alexander Hunter Murray built Fort #Yukon, on the Yukon River at its junction with the Porcupine. It was the first of two posts to be built on the Yukon River--Robert Campbell built his Fort Selkirk shortly after Murray built Fort Yukon. #Journeys #ThreeJourneysNorth #NoOrdinaryRisks nancymargueriteanderson.com/fo

    In 1850, the steamer Beaver hit a submerged rock on the West side of Vancouver's Island, and damaged her keel badly enough that she had to be taken out of service. Interestingly, this accident seems to have been connected with the trade at Fort Selkirk on the #Yukon River, when some expected Indigenous men did not travel from the coast into the interior. #Journeys #ThreeJourneysNorth #NoOrdinaryRisks nancymargueriteanderson.com/ac

  11. Some of the wildlife here is a little bigger. And some is just small, black, and fuzzy. #wildlife #yukon

  12. NO ORDINARY RISKS: THREE JOURNEYS NORTH TO THE ARCTIC SEA
    In 1847, both measles and dysentery arrived in the Columbia district, and spread everywhere, following the brigade trails North, and the seacoast all the way up to the #Yukon, via the massive Indigenous Rendezvous held every year on the Stikine River. The diseases killed thousands of Indigenous people. #Journeys #ThreeJourneysNorth #NoOrdinaryRisks nancymargueriteanderson.com/me

  13. “People are very aware that they can’t have standing garbage on their properties,” Oborne says.

    “They really understand what you need to do to keep the community safe and keep the #bears safe.”

    What books featuring nature or the great outdoors come to mind?

    My favorite books about the "great outdoors" right now (and some of my fav books right now), are by Kelley Armstrong. The Rockton series and its sequel series, Haven's Rock. Set in Canada's Yukon, these are small communities of people living almost totally off the grid (for reasons).

    They have strict community rules (for acceptance & to stay).

    It's no easy life.

    In the Journal of Occurrences of the HBC's post, Fort Selkirk, we can read of the difficulties of keeping alive and well in a country so far from any other community that they must be completely self-sufficient--not an easy task in the North. #Journeys #NoOrdinaryRisks #Yukon #ThreeJourneysNorth nancymargueriteanderson.com/fo

  16. @jimfl You can also do a loop: Drive to Skagway, Ferry to Haines, Drive (back towards Skagway), or in opposite direction. Best to make ferry rez.

    If you have time, I recommend visiting Hyder/Stewart in the Misty Fjord National Monument off of Cassiar Hwy. Pretty cool place.

    Dont forget to bring the Calvin and Hobbes book about the Yukon"

    Adding hashtags so others might join in with even better recommendations.

  17. NO ORDINARY RISKS: THREE JOURNEYS NORTH TO THE ARCTIC SEA
    From Finlayson's Lake, north of Frances Lake, Robert Campbell and his men carried their provisions over the low height of land to the banks of the Pelly River, and then canoed down that river to his new post of Fort Selkirk, on the #Yukon River. #Journeys #ThreeJourneysNorth #NoOrdinaryRisks nancymargueriteanderson.com/fi

  18. NO ORDINARY RISKS: THREE JOURNEYS NORTH TO THE ARCTIC SEA
    In 1839, Robert Campbell made his first journey up the violent and rapid-filled Liard River to Frances Lake and on to Pelly Banks, on the Pelly River in the #Yukon. No other HBC man had made this journey before him, but many would follow this trail North in later years. #ThreeJourneysNorth #NoOrdinaryRisks #Journeys nancymargueriteanderson.com/li

  19. NO ORDINARY RISKS: THREE JOURNEYS NORTH TO THE ARCTIC SEA
    When Robert Campbell met the Stikine Chief Shkes, at the rendezous of all the First Nations in the region, he was unaware that that same Indigenous Chief had already chased off another HBC man earlier that summer -- Peter Skene Ogden. #ThreeJourneysNorth #NoOrdinaryRisks #Yukon #Alaska nancymargueriteanderson.com/st

    Sometime in the early 1850's, James Anderson described the river route into the #Yukon, with notes and descriptions taken from Robert Campbell's correspondence. #ThreeJourneysNorth #Journeys #Yukon #NoOrdinaryRisks nancymargueriteanderson.com/li
