Dug fence posts in my yard a few weeks ago through glacial till. I saved as many rocks as I could, soaked them, washed them, made a little rock river in my garden. Rainier Valley in Seattle.
All of Nick's presentations are wonderful, but the field trips are special in that you can see the actual material. It really brings home the point of the lesson.
I grew up on the west side of QueenAnne hill in Seattle, about 250 feet above sea level. Can't imagine 1000 feet of ice. I have a hard time wrapping my brain around 16 to 19 thousand years ago, too.
Continental lobe came out of Canada to the northern Olympics and created a dam. Creating a large lake in Puget Sound. This happened many times. There are many interbedded deposits of lakebed clays. As far as the pebbles and gravels go, when clean you should suspect outwash. When dirty you suspect glacial till. No clean rounded rock fragments in glacial till. The pebbles in the lakebed clays are the drop deposits you mentioned. Special situation.
I grew up just off the bluffs and beach near Federal Way. Used to make potter's clay out of the stuff. Spent hours and hours on the beach looking at the bluffs and the gravel that made up the beach. I think it seeded my budding interest in geology.
Thanks to Nick I now have a part of my brain filled with terms like: glacial outwash and till. I'm going to be right at home when the geology convention comes to town. Thanks to these lectures, I can see my surroundings in a clearer light. Much appreciated, Nick.
We used to have property in Yelm, which you mentioned as the southern boundary of the ice sheet. The ground in Yelm is all rocks and very little soil. Very hard to garden with all of the rocks.
Yes Nick, I'm still with you, just like everyone else. And just like the others I'm loving all you do. Gratitude is a small word and hardly describes my appreciation. Thanks again. LOL. Pete on the Isle of Wight. PS We need a few more like you.
Pretty interesting to me since I live on a hill south of Seattle on Puget Sound that is glacial till, so I can see exactly what you mean in my yard. Pretty cool!
At the wrap up to your observations there was a shot of rocks washed out of the clif there was a rectangular red piece of urbanite. Althou anthropogenic it is a part of the story as it was likely made of that same grey clay.
My personal moment of triumph was recognizing the granitic nature of that pebble before Nick identified it as granite.

ONE LESS THING
I never thought that I was going to get so much from your videos Nick.

Great stuff! Thanks from Jane in England.
I learned a lot thanks. All those bluffs from the ice sheets and so far South!
thanks again Nick.. im learning so much

I like the observations. Makes me be more aware of what I'm seeing.

Wonderful video. Thanks for teaching us so well! It feels like such a privilege to go on these outings with you and to come away so well informed!
Thanks Nick! I’ve seen those bluffs for many years... now I understand them a bit better...great program! 👍👍

Bloody good teacher, right voice, interaction, and the requisite knowledge to present his science in 'a matter of fact' way.
