In Marquette, Michigan, there's a park with some bizarre, pillowy-looking black rocks. To understand where they came from, I found an expert, who took me on an adventure to (literally) stand on the Earth's surface as it was a billion years ago.

I'm a freshman in highschool i and just want you to know you have become a huge inspiration in my life. Your channel has helped me to reach out and learn so many new things that i used to just ignore. I just wanted to say thanks for showing me a new side to the things i used to look over.

@vicbertfartingclack4559 Год назад

Geez. I got the chills when Dr. Cannon talked about standing on that same regolith surface 1 billion years ago vs now ! How is that not utterly mind blowing?! I love anything that covers deep geological time. Thank you once again !!

@AlexisDahl Год назад

Right?! I was absolutely blown away by that. All this time, I've just been parking my car there and walking right past that spot.

@RoxnDox Год назад

The whole concept of ‘deep time’ is the most mind blowing part of geology! And once that concept hits you, you truly can look at the universe in a different way. @Alexis, another wonderful historical geology lesson about your neck of the woods!

@VoIcanoman Год назад

Nice to see Dr. Cannon in one of your videos again! People like him are awesome, and I've been privileged to know a few of them - for example, I took a geolimnology class ~20 years ago from the world's foremost expert on Glacial Lake Agassiz, who currently lives a 5 minute walk away from my house, coincidentally (for someone who studies lakes) on a street called Lakeside.

@AlexisDahl Год назад

It was exciting to work with him again! Also, that sounds like an amazing person to learn from!

I just found this channel and have watched several of your videos already. The production quality and videography is on par with a much larger channel. You are able to make these videos very entertaining and informative. This channel is going to be huge.

Thank you! I appreciate the kind words! RU-vid has been recommending a lot of my videos recently, and I'm very curious where that trend is going to end. 🤷🏻‍♀️

@apex107lrp Год назад

I had her channel pop up on my "suggestions" just a few days ago. She mentioned having seen several comments to that effect...and if I'm right her subscription numbers have been shooting up up up since my first view earlier this week or so. On watching my first video, I glanced down expecting to see a subs # 10 or 100 times greater. Her professionalism, enthusiasm and wonderfully produced videos most definitely deserve an enormous audience.

I live in Michigan too and have an affinity for the UP but I've spent most of my time in the Eastern UP. Your videos make me want to plan a couple trips to the west side too! Seems like you've gain almost 4000 new subs since you channel was recommended. That's awesome! Congratulations! You'll be getting a silver play button before you know it!

@testbenchdude Год назад

Part of the reason I love geology is the story that it tells. Deep time is at first an abstract idea, but once you get to know it, you begin to understand things on a geological timescale. And it's just awesome. Thanks, Alexis!

Greetings from Belding, MI. Recent subscriber here. Just wanted to say how much I'm enjoying your videos. It's great learning all these fascinating things about my home state and your enthusiasm for learning and discovery is infectious.

My jaw DROPPED when I realized you talked to Cannon himself!!! He has made COUNTLESS geological maps of the Lake Superior region, including some I have used in my own geologic research!

@AlexisDahl 4 месяца назад

He's a rock star, for sure! There have been countless times I've been trying to read about other topics, clicked on a paper, and gone, "WF Cannon - classic!" 😂 I'm grateful to be able to collaborate with him sometimes!

Only came across your videos a few days ago and subscribed right away. Very informative work with such a great attitude. Fit in perfectly with my New Years resolution to avoid as much as possible negative news and videos. Hopefully some day you can make some field trips to our Canadian Rockies. Love to hear your input about them. Keep up the great work!

@AlexisDahl Год назад

@@AlexisDahl Good to hear. The road from the Trans Canada highway to the Columbian Icefields & Jasper is rated as one of the top 10 scenic drives in the world. Definitely worth checking out. There’s also the Kananaskis area that’s a bit closer to Calgary and has another great scenic drive through the Highwood Pass area.

I went to college at Northern Michigan University for 4 years and Presque Isle is one of my favorite places in Marquette! During the fall I would bring my homework to black rocks and just sit there and listen to the sounds of Lake Superior while doing homework 🙂 also all the trees around Presque isle are beautiful when the leaves change color in the fall

Hi Alexis ... excellent video. Such GOOD stuff! So great to see Dr. Cannon again. Serpentine is the California state rock ... pretty cool. Olivine is also present in the subduction process --- not to say the UP is undergoing subduction -- No. Maybe at one point in geologic history ... it did! I think this region was once an ancient suture/terrane spot where there was a lot of "smashing" going on. Not many folks know just how AMAZING Michigan geology is ... Keep up the great work!!

I especially am interested in the Sudbury impact, and want to visit that roadside park you were at. Hard to believe I played on billion year old rocks and didn’t even know it! Btw, one of my favorite places on earth is Brockway Mountain and the loop from Eagle Harbor and Copper Harbor. Thank you for these!
