YOU ARE AN AMAZING INSTRUCTOR. YOUR VISUAL INSTRUCTION IS EXTREEMLY WELCOME. SPENT 33 YEARS DOING GEOTECH WORK FOR USFS. SELF TOUGHT. YOU VISIT SO MANY PLACES I HAVE WORKED IN. MY SON IS GRAD FROM CWU. I SUGEST YOU DO TRIP TO RHYOLITE DIKE IN FIRST CREEK ON SOUTH SHORE OF LAKE CHELAN " WOOD STONE". AS WELL AS GLCIATION. CAL BLACKBURN
Nice explanation !!! Ice age ... fascinating subject. ... Glaciers as well. We have "*drop stones" in Adelaide exhibited ... embeded in a mud of a glacial lake ... ... All coming from Antarctica direction ...( victor Harbour...)... during Gondvana glaciers 280.000.000 y.a. .and droped from floating icebergs. ...as well as few erratics droped onto todays bech line in Halley cove beach. Article: * " Boulder lags in Rosetta Bay at Victor Harbor, South Australia" "What’s the significance of the large granite erratics scattered through the Inman Valley in South Australia?"
Love these videos, thanks so much for your work! Do you find other erratics located at the exact same sea level assuming the flood waters were at that level for a while and the ice would have all floated on top of the water?
Please forgive my ignorance, but if the flood basalts are the "bedrock", what did they flow over and cover? (and why aren't those considered the "bedrock"?). Sorry for my confusion.
WTF, I swear it seems like I've subscribed to your channel about a million times now (ok, maybe not quite but still...a lot). Is UA-cam messing up or are you on lots of channels maybe or...? Meh, thanks! Enjoyable as always, love your teaching style!
PS) I have some rocks in my front yard I've been trying to identify for a while now and am no closer than before I started. One broke open and the inside is completely different from the outside but not like a geode. The rocks aren't rounded like geodes. The inside doesn't look like any geode innards Ive ever seen. *Looks* almost like the lumber at the hardware store except the light color is slightly more yellowish and the "growth lines" are a bit more orangish. They alternate like tree rings but I don't think its wood nor petrified wood...though thatd be my closest description so far...wood on its way to being petrified or something. It appears to have a grainy texture so Id guess a sandstone maybe? The rock as a whole is heavy as I'd expect but the piece that broke off from just the inner portion feels much too light for its size, too heavy to be wood but not heavy enough to be petrified wood. Any direction would be much appreciated!
Nick great your stuff of Washington State. These igneous erratics are strongly felsic themselves with breccia-like inclusions no doubt. Plagioclase feldspars are zenoliths in part having crystalized at higher temperatures, before anyother mafic crystals develop ?
Great older programs. Nick, you're just a baby here! Love these.
When you start to watch a video before class and you've already upvoted it... 😊💖

Hey this rock has a chunk broken off. Nick must have been here.

THANK YOU FROM VT
I imagine the mineral collecting must be great in Washington..
Amazing😮
Nice area. Spent allot of time messing around there.
Sick intro dude 😎

Well, if you think about it, all bedrock has something underneath it. Now the lava is just the top dominant layer of bedrock.
spectacular

nickzentner.com has all of my stuff in one place. Thanks for your interest.

Sounds like petrified wood to me.
Cool!
Add Washington to places to visit for rock hunting.
Don't forget Washington creeks👍🏼❤
Come visit.
@@lynnmitzy1643 Agree.

+David Laing
Thanks David. The erratics are pretty typical granites with minimal inclusions.
Where can I find columbia basin agates in vantage?
At Richland the river elevation is 336’. How can the river be higher further downstream where you were at?
❤
Plagioclase is found in many parts of the world.
Can we get some new vids by chance?
nickzentner.com Thanks.
