I have never cared about geology, but Nick Zentner makes it interesting. Great video, too.

Years ago, we stopped at the Ephrata fan area (close to the airport) and marveled at the thousands of mostly round boulders. Walked among them for hours speculating on how it all happened and where they came from. Mystery solved! Thank you.

Great tutorials on our natural wonders. Thank you!

Brilliant presentation of a complex geological phenomenon! Thank you for sharing this informative video. Washington State is the most interesting geological place to live.

Hard to resist these videos if you are a curious person.

The ice age floods and the geology of all of Washington state are so cool. Big thanks to Nick Zentner for making so much amazing information so accessible!

wealth of knowledge and yes cannot stop watching these geology videos

Great stuff Mr. Zentner. Thank you.

Great photography and a cool story

Washington state has the most interesting geology in the US. I'm a truck driver and love driving in Washington.

Thank you so much for a great presentation!!! I was visiting Dry Falls Area last August and was so impressed !!! I love geology of WA!!! Its so unique. You explained so many interesting facts!!! I wish I had teacher like you when studied geography in Poland many years ago.....

Dry Falls is an amazing place. Had the privilege of visiting there a few years ago along with Mt. Rainier, Lake Chelan, Seattle and all points in between. Great video.

This was great. Thank you.

Excellent presentation! Thank you.

I love learning about geology. Took a class in geology at Everett community college in 1980...Just no jobs in the field back then...so I got a degree in civil engineering. Geology really helps in the understanding of soils, foundations and drainage.

I love Your Doc/Vids. I watch them twice sometimes. There has been an amazing history here in Washington. .

Great video and the perfect length. We don't have much for rocks here in Florida but it's fascinating stuff. Like a good detective story but real. Thanks!

Outstanding video and explanation. I first encountered the fascinating story of the ice age floods many years ago when I read of the life and explorations of J Harlan Bretz. Your videos are so informative and interesting. Thank you.

Grew up in this area back in the 50s and hiked and camped in all these places. Always was very curious myself about all these unusual formation. This series is one of favorites and Nick is my all time favorite geology teachers.

what a great series,great great instructor
