After a couple of cooler days, there's now the thinnest layer of snow on the mountains, the same ones that are almost visible in the clouds from last week's hike
Photo of an alpine landscape facing south-west towards Haute Savoie in France from a point above Montreux. The foreground has trees, with forested alps in the background reaching into an overcast grey sky.

In case anyone needs a bit of extra luck, have a four-leaf clover
Close-up photo of a grassy patch of ground with clovers. Centered is a four-leaf clover with some dents to its leaves, but still hanging in there.

Fern appreciation post! Maidenhair spleenwort and wall rue, I think. #fern
Photo of a magnificent individual of maidenhair spleenwort (Asplenium trichomanes) growing on a stone wall Photo of a fern with club-shaped leaves, likely a wall rue (Asplenium ruta-muraria), growing on a grey stone wall. The spore-containing sori are visibile under the leaves of another individual in the background.

Saw, among many others, the painting "Paisagem com Ponte" (1931) by Tarsila do Amaral at an exhibition last year. I find the clear lines and colours beautiful, and the nonsensical perspective quite funny

Photo of the painting "Paisagem com Ponte" from 1931 by Brazilian artist Tarsila do Amaral. The painting is of a landscape featuring a bridge over a body of water (a river?) in the foreground, that leads to colorful houses on yellow-brown spoil.

I found the crocus on the north slope of a hill, at nearly 1100 masl, which seems a little extreme this early in spring

Unknown bird of prey the size of a rugby ball #birdwatching #nobinoculars #cantseethatfar
Photo showing the silhouette of a sitting large bird against a grey afternoon sky. The unknown bird is perched on top of some equally unknown leafless shrubbery. The bird is about the size of a rugby ball and heavy enough to bend the branch it is sitting on.

Beautiful, if cold, morning commute
Photo of a bicycle leaning on a wooden power line pole on the side of a small rural road. Behind the bike and the pole are pastures covered in a hazy mist, and there is frost in the grass. The sun is just high enough to shine through some trees, bathing the scene in warm morning light.

Prompt: post a photo without explanation to bring some zen to the timeline. Close-up photo of patterned leaves of an Calathea Makoyana houseplant. There is a tiny jumping spider perched on a leaf. Don't tell anyone.
