Would be isotopically so interesting if accessible.

I laughed. And probably best it’s a different Brent.

I bought my copy from Aquila books in Calgary. Not sure if they’re still there.

Not sure if you ever read Lew Green’s excellent ‘the Boundary Hunter’s’ about A.O.Wheeler, Ogilvie and the late 19th and early 20th C surveyors of the AK border. 141st Longitude and AK panhandle. It’s a great read.

There’s a book by Frankfurt (it’s quite short) called On Bullshit that’s worth a read.

Yes. And I doubt they will ever go back. Mixed feelings about it. It’s definitely efficient. Though this year with some complex family needs it was welcome.

In a crazy multiverse sort of way, there will be those that have greater success with changes at NSF.

A very cool ancient eDNA paper from Tyler Murchie’s PhD that shows the co-occurrence of distinctive plant, animal, microbial and even gut microbiome communities associated with megafauna and their extinction/extirpation.

Permafrost microbial communities follow shifts in vegetation, soils, and megafauna extinctions in Late Pleistocene NW North America
Using sedimentary ancient DNA from permafrost sediments deposited between 30,000 and 4000 years ago in Yukon, Canada, we explore whether there were changes in microbial communities paralleling the tr...

Relict permafrost preserves megafauna, insects, pollen, soils and pore-ice isotopes of the mammoth steppe and its collapse in central Yukon
In eastern Beringia (unglaciated Alaska and western Yukon), the Pleistocene-Holocene transition was characterised by rapid changes in plant, insect an…
