It's Back: The Natural World Forum

Thank you Ryan!

That photo has a beautiful composition.

I am fascinated by rocks as well. From studying horticulture and soil science I learned enough for me to want to know more. One basic bit is that boulders, cobbles, pebbles, gravel, sand, silt and clay are just definitions of size. Clay is the most fascinating to me; so small and flat with a big surface to volume ratio that is has a (negative) charge which is how and why Calcium and Potassium ( and other cations)  stick to it. The polarity of water also makes it stick to clay, which explains what clay does to soil and why we get it stuck on our boots . Really cool stuff :)

Awesome forum :-) Thank you!

A week ago I found out about the Frost Flower and got some photos of it. Frost formations on some of the stems are 12″ in length. Since I got the photo, the weather has been too warm to see if they will occur again on the same plant stems.

Gorgeous photo, Ryan!

Also, interesting to learn about how clay works and that frost flowers are a thing. This topic delivers!

Thanks for bringing this back.

Nice shot of Medicine Bow Peak.

Dan, I was wondering why you showed pictures of a feather, when I realized…

Andy Goldsworthy does stuff with natural materials that then break down in the environment. But really, we see natural formations that rival art, or surpass it, and sometimes only last until the morning sun strikes, or a season–or for aeons.

It was amazing to see the curvature of the ice formation. I was there at the right time. A couple hours later they were gone. Have not had freezing temps since then to witness the little miracles again.

Great to see this forum back.

Here is a GREAT TED talk about how forest ecosystems exchange information by a Canadian scientist

Watch it and learn something new.

Glad to see it back. Thanks Ethan for having the idea.

Also: The Hidden Life of Trees is a remarkable book that also details the sophisticated forms of communication that trees use between themselves in a forest. Who knew? Lots of other tree related stuff as well.
