Went looking for quartz over the weekend. I was lucky to find a nice untouched pocket with well-formed crystals (after 3h of search!). The first picture shows the cluster in situ within the crack and the other one shows the same crystals as a detached piece.

🥝 The kiwi harvest is the last one of the year in the garden.
Happily surprised by the quantity given the very moderate bloom in spring.

There are only a few things in life cooler than crawling inside a lava tunnel.
Incredible geological formations, narrow sections followed by rooms with over 3m high ceilings and pilars.

Cold blurry colors for a cold morning hike at dawn. We hoped to hear the deer rut calls (Brame du cerf in French) but the mountain remained silent today.

Sichuan pepper from the garden, that's the 2nd year I get some berries.
Smells incredibly good.

Quartz crystals harvest in Alpine granite cracks with 8 yo during the last weekend.

We got lucky to find some nice specimens!

Perfect weekend for spending a night in a mountain hut in the Swiss alps to escape the heat.

Is this zucchini trying to send me a message?

Ouch, that's a 2009 version of me on the screen with still some hair on the summit of my skull 🤣 . Should send Triana a more recent image 😅
