At first glance through the interminable TOC of the latest Geophysical Research Letters I misread the title of this paper and was briefly buoyed by the thought of GRLs' foray into women's health.

A tiny but tangible example of how government dysfunction degrades educational opportunities. NP closures meant replacing hikes with road cuts. Still, no one can take away the beauty of NM sunsets

Another great day on the rocks, culminating in another New Mexican sunset.

It's eolian time. How about some small-scale eolian sand stratification (grain flows, grain fall, and translatent; from the Miocene of Argentina) contrasted with the lack of any such features (other than conchoidal fracturing) in this massive loessite (Permian of Colorado).

Took a walk along the lake and ran across this paleosol (Permian Garber Fm)...sporting some great root traces.

Imagine how jiggly this sand must have been when newly deposited, as water escaped to form these dish structures. (A boulder from Cretaceous turbiditic strata, Southern California)

And now for more weather in a (deep-time) rock: inferred ice crystals from ca. 300 million years ago, a sort of lagerstätte, preserved in the Usclas Fm (France). For more details, see pubs.geoscienceworld.org/gsa/geology/...

New semester teaching paleoclimate, and depositional systems, so here is one of my favorite rocks, archiving both weather and climate: a dust (loess) deposit with raindrop imprints (largest ~5 mm diameter). Permian Maroon Fm (CO), recording a light (afternoon?) shower of some 300 million yrs ago.

Okay, this is very basic, but...there is nothing unusual about rivers flowing north.
Ok folks: what is your favorite fact that you share with people (maybe a bit too) eagerly?
