Rockhounder's club (on topic)

I enjoy getting out in nature, but I also like to be doing something to really get the full outdoor experience. This thread is for anyone who likes to get out and look for cool rocks. Discuss your methodology, favorite types of rocks and locations for searching, post pics of your favorite finds.

To get started, I like to walk rivers and streams, do a little snorkeling, comb gravel bars. Mostly find agates, jaspers and petrified wood, some quartz crystals from time to time. Here's a few of the pics I just happen to have on my device at the moment.

On the left is what I believe to be a holly blue agate, next to a redish stained agate for contrast.

Top left is a piece of red carnelian agate, the rest are sunstone feldspar crystals.

More to follow....
My wife loves Beach glass.

Have you seen that new yooperlite some dude in Mich discovered? Glows under ultraviolet light.

There are a lot of minerals that glow with a black light and uv. It's one way to help identify different minerals. The glowing is usually caused by phospherous or fluorine compounds in the mineral. I've read that sapphires and emeralds fluoresce.

Wtf is a ‘yooper?’ Lol

Yoopers are people who live in the Upper part of Michigan---the UP. If they had their way they would become their own state. Look at a map of Mich. ---the state is made up of 2 separate land masses. I can't blame them for not wanting to be associated with Detroit- Flint or any of the other scumbag cities to the south.

Sapphires, emeralds and rubies are all corundum.

They are more Canada than they are Michigan.

You know what else does when sprayed with luminal and lit with a black light. Bodily fluids.

Nothing special to anyone else. But here's a handful of stones my sweet mama recently brought home from a trip to the motherland (Poland)

Emeralds are green beryl, and are more related to aquamarine, which is blue beryl. Rubies are red corundum, all other colors are referred to as sapphire.
Oops. You are right. Rubies and sapphires are corundum and emeralds and aquamarine are beryls.
 
My daughter likes beach/river glass, and she really wants to find some arrowheads. I've given her every piece that looks like it might have been an arrowhead, but I have yet to find a complete one.
I found some when I was a kid, dont what happened to them we used to go digging and find lots of cool stuff .

This is two pics of the same rock, I believe it to be Alaskan jade, my dad brought it back with him when he took a trip up there.

Same rock, just trying some different lighting conditions to get some good pics.
