Erratic Boulders - Rafted in Icebergs by the Ice Age Floods

Erratic boulders are scattered throughout the Ice Age Floods region. Many of the boulders resting on the younger Columbia River Basalt flows were transported within icebergs from the Rocky Mountains. Floodwaters from Glacial Lake Missoula swept over eastern Washington and down the Columbia River Gorge at speeds in excess of 60 miles per hour. The icebergs that carried the erratics often drifted into side channels during flood events. The stranded boulders now look out of place, grounded high on canyon walls above the scablands.

    You make me want to go back to school and scratch that itch I felt in Geology 101. You are an inspiring teacher; your passion is infectious.

    I live in New York and I have a glacial erratic in my yard. It’s a huge boulder that doesn’t fit anything around. It’s pretty cool. Like 8ft tall. I climbed all over it as a kid.

    My class loved this - we are studying glacial erratics so we are delighted to see a different persective of rafted erratics - thank you.

    Good job dude! I wish I had one of those Rocks in my yard. To think a meteor strike caused the ice to melt is an amazing discovery.

    I had never heard of the theory of rocks caught in icebergs that were pushed loose from glaciers in flood events. Very interesting. Thanks for the info.

    Very good video. I like seeing erratics from other parts of the world. I live in Alberta, Canada, and we have the Foothills Erratics Train but I believe they are quartzite and are definitely glacial. I even have a series of Geocaches pointing out 8 or 9 in the area where I live. (You probably know of the Big Rock, near Okotoks, Alberta--which is by far the most massive glacial erratic in our province.) I really love this stuff. Please continue with your excellent videos.

    Thank You, Vary Interesting and Informative. I currently live in the N.E. of the country and the N. E. of the state of PA. I beleive my area has both Ice Rafted Bolders and BullDozed into place Bolders. I sure could be wrong about the BDBs. This being the case, if Mr. Red Bow Ty would care to comment on this and pass on his wisdom, it would be vary nice and informative, along with educational too......

    so what are all the small rocks that dot the landscape near rocky ford euphrata area. are they erratics too or were they just lifted in the current of the floods?

    ***** You're asking about the Ephrata Fan, an impressive pile of rocks at the mouth of the Lower Grand Coulee. The rocks are all from the Ice Age Floods for sure, and most were tumbled down the Grand Coulee by the water and then dumped near Ephrata as the floodwater slowed when spreading out into the Quincy Basin. Maybe a few ice-rafted erratics, but most were simply tumbled in the flood water. Good question. Thanks.

    Metamorphic rock that used to be shale... Billy Yelverton can make that in his lab in about 10 seconds... :P Clearly showing it can be changed pretty fast from one rock type to another. He can even make high grade Dolomite from simple sand and dust.

    Basically a glacier blocking Clark Fork River and forming a giant natural lake reservoir during the last ice age. And then the ice dam breaking and releasing all of the lake water within a few days.

    Love the geology. Not a fan of the format. Two minutes isn't really enough time to cover very much of the complex nature of Washington state geology. Also not a fan of the bowtie (too much resonance with Bill Nye the pseudo-science guy.) And why are you addressing your audience as "young people"? That's just strange. When the camera pulls back on your "downtown geology" audience I see lots of grey hair and not many who look like young college kids trying to get some extra credit or some remedial understanding that they should have gotten in Geology 101 at CWU. Give us the real Nick Zentner and a full dose of the most exciting geology on the planet, not quirky Bill Nye showing us a pretty rock, then exiting the stage quickly to make way for the next act.
