Video showing the collapse of the Pu’u ‘O ‘o crater floor on March 5. The video starts at 4 am and ends at 11 pm. The floor of the crater dropped about 115 meters (377 ft) in just a few hours.
Caddis Fly Larva - Wildscape
Caddis fly larva live in streams, building themselves little shells of whatever material they can find. As a child I had a little collection of these found in the stream in the woods near my house, little inch-long tubes of tiny pebbles or bits of stick; Wildscape created an artificial stream, seeding it with bits of various materials (opal, in this instance) for their captive caddis flies to use in building their shells. I posted another example here.
"Most of it is tumbled rock I’ve bought over the years. Some are rocks I’ve picked up, though most of those are gone now as I move around a lot. I do have some other rocks, but they are with potted plants. Have fun guessing what is what!" - emsnippet
I can’t even deal with these, they are so cute.
I just realized that I’ve very-nearly hit 50 followers, and I don’t know a thing about you all! In an effort to get to know you better while making this blog a little more interactive (and a little less reblog-heavy), I’m thinking of introducing a simple ‘question of the week’ where I ask you guys mineral/rock-houndy/geological-related questions.
What is you favourite mineral?
A sphere of fluorescent amber from the Dominican Republic (see https://www.facebook.com/TheEarthStory/posts/588657784528603) has been carved in the Chinese style into a sphere with rampant sky dragon couchant, presumably flying above the waves of an unknown sea that have been ingeniously carved to form a base.
