New paper! We look at ocean conditions in the Gulf of Alaska/N. Pacific during the last glacial/deglacial to try and discern whether certain time periods were more/less favorable for human movement along the coastal route from Beringia into N. America: pnas.org/doi/10.1073/pn…

I also thought I’d mention that the ages for human presence at @WhiteSandNps are compatible with one of our proposed ‘viable time windows’ for a coastal migration. We highlighted the interval between 24,500-22,000 yr ago as one such window. pnas.org/doi/10.1073/pn…

Thousands of footprints pepper the salty expanse of White Sands National Park, preserving ancient vignettes in the sand. Now, a new study bolsters the controversial claim that humans left these tracks ~21,000-23,000 years ago! My latest @nytimes nytimes.com/2023/10/05/sci…

Congratulations to my @USGS colleagues: @kathspringer, Jeff Pigati, Dave Wahl, Marie Champagne, and all the other coauthors on their excellent work in getting additional pollen and OSL dates on the White Sands Footprints! This is a game-changer!

Big news: USGS scientists & partners have confirmed, with 2 new lines of evidence, that human footprints found in White Sands Nat'l Park show that people lived in North America 21-23,000 yrs ago—much earlier than previously thought! More here: ow.ly/9peJ50PTBGN Imgs: NPS

Whooaaa check out this cool new paper out today in @NatureGeosci 😎 AND it's open access?! Absolutely thrilling. If you're interested in the 100-kyr problem or orbital forcing on glacial cycles, please give it a read 👀 nature.com/articles/s4156…

One of my favorite finds in #Rome after #INQUARoma2023 wrapped up, was the Pietro Canonica museum in the @VillaBorghese. The funerary monuments (such as The Gust of Wind) were particularly haunting, and #TheAbyss sculpture was truly a masterpiece. Plus I was the only one there!
