Dwindling snow threatens Greenland's dogsled mushers' ancestral way of life.
Snow has become so scarce on Greenland’s east coast that even short dogsled journeys now break down, making the business of running dogsled tours increasingly economically unviable

I went trout fishing late summer (catch and release of course), and along the banks of the creek were stands of goldenrod mixed with the most pungent native mint you can imagine. Goldenrod has a bad rap.
Of course I paused to take some photos.

Ponderosa pines are one of my favorite trees because of their prevalence where I grew up and currently live, my mother’s studies in the same area (PhD plant physiology), and a childhood fascination with their puzzle bark.

‘The Temptation of St. Anthony,’ someone who is clearly unfazed and not tempted by pesky demons.
A masterpiece engraving created around 1470–75 by Martin Schongauer.
He was also called Hübsch Martin (pretty Martin) during his lifetime. The two decades younger Albrecht Dürer collected his art.

Another painting,
St. Mary Magdalene by Italian painter Pietro Perugino. Apparently Michelangelo told Perugino to his face that he was a bungler in art (goffo nell arte). That’s one opinion.
The model is unknown.

Pegmatite is a type of igneus rock that frequently contains large crystals of quartz, feldspar, or mica. When looked at with a longwave UV flashlight, these minerals seem to glow! Kids at our museum can see this for themselves up close and personal.
