the color of the day is orange

Some of the mushrooms are being attacked by a white mold.A mushroom growing out of the ground.

A fire tower on the summit of a mountain. The peak is solid rock with only a few pools and barely any vegetation. A group of people stand around the base of the fire tower. The bright blue sky is mostly clear with a few clouds.Looking out across a mountainside and valley. The mountain is solid rock, and the valley below is slightly hazy.A small pool of water between two rocks. A rust-red biofilm is growing in the water, and some of the color is dried up on the sides of the pool. A rock sits in the middle of the pool—it, too, has the rusty biofilm climbing up its side.

Went to a bog.
A wooden walkway snaking through a forest.Two purple pitcher plants on the bog.Wide angle view of the bog: no trees grow on the surface but are visible in the background where they grow on solid ground. The surface of the bog is covered in plants like moss, flowers, and small shrubs.

Two loaves of sourdough bread sit on a wire rack in front of a window. Outside the house, there’s a little bit of melting snow on the ground and a rosemary plant in a planter.

This week for book club I'm reading "In The Land of Ninkasi" by @tatepaulette.bsky.social! I've really enjoyed it so far—it's neat to be able to learn about this culture through their beer tradition. #nowreading

oh man you can do all kinds of stuff! i usually have some kind of veg ferment going, here's a pic of the sauerkraut i started a few days ago. at its simplest this is just cabbage and salt, plus spices if you want. i did this in a vac bag but a jar works just as well.
