Badges and certificates don’t mean much to me, but this badge does. Glad to be considered a Nature Journaling Educator by @wildwonder.bsky.social !

Taking a class from them this summer was one of the highlights of my sabbatical.

Sketching owls. This helps me know the owls better. Also having fun experimenting with different media.
A detailed sketch of a short-eared owl perched on a branch is accompanied by handwritten notes detailing a sighting in South Dakota. A sketchbook page features three colored drawings and one grayscale drawing of various owl species, with handwritten notes and dates accompanying each illustration.

Taught twenty students how to make Adirondack chairs today. It was part of a class taught by our Registrar, and hopefully these chairs will provide a nice outdoor study spot!

Northern lights over Sioux Falls right now. They’re dim, but reach across most of the sky, and your phone will really highlight the colors.

Serviceberries in my garden, yesterday and today. Today my garden got its first blanket of snow.
Golden and orange leaves densely cover branches against a dark background. Snow-covered brown leaves on a tree or bush create a wintry scene.
