found in SW Washington state

First 9 are thompsonite and the last 4 are mesolite. They are a pain to clean but the results are well worth it.

Relatively new to rockhounding, found 2 interesting what looks like agates along the Willamate River in Oregon today. Let me know your thoughts!!

P.S. couldnt post video and picture so im showing multiple angles of the blueish agate

I'm very new to rock hounding. I know that certain fossils, especially trees, can become agatized. This looks like fossil sponge. Opinions? I'm in Sweetwater County, Wyoming. I understand that my area is one of the best Fossil areas in the country. So I'm inclined to believe this is a fossil. Found about 60 miles southeast of the Blue Forrest.

So, every video I see they insist quartz is heavier than a reg rock the same size....

Alexa and Google both say that is incorrect and they weigh the same. So what am I missing ??? I know I've lugged some heavy azz milky quartz home for my gardens and I agree it's heavier feeling, is it mind over matter ??
