Glacial Geology of Long Island

This is a lecture that explains the geological origins of Long Island during the last ice age and relates glacial processes to Long Island landscapes and habitats.

Nice comprehensive lecture....I am a Geologist living in Queens and I am impressed with the scope of your presentation.

Fantastic lecture! I’m a local rockhound and I find so many interesting specimens on the north shore near the Harbor Hill moraine - the amount of beautiful multicolor chert and quartzite with mineral inclusions you can find there is stunning. And the occasional brachiopod impression! It’s like getting a peek into the travel and pressure of the glaciers that formed LI over all that time.

We have an esker in our town, it's called great esker park, just south of Boston, I love seeing these animations and learning about the long island area, it's fascinating how our land is built, great job. Thank you very much.

I enjoyed your lecture. I grew up near Lake Success (1960's) always heard stories that Lake Success was "bottomless." As a child, my grandmother would make the trek from Brooklyn to swim in the lake. I guess 100 years ago it was open to the public.

I lived on Long Island for 45 years … and just learning all of this great info with you … gratitude and blessings for putting this out on YT !

As a Long Islander, I'd like to posit that I think that this island is a giant geographical timestamp that marks the full extent of the Laurentide Ice Sheet in this area represented by the Ronkonkoma moraine, and the Younger Dryas return of the ice as seen on the north shore and north fork. Just my opinion. Great lecture, thanks for sharing.

Good lecture, been looking up long Island and south seaside towns of CT. Moving again one day, I'm always curious about the land, elevation and possible floods.

Very good.

I remember seeing purple sand in the hollows of eind blown sand.on the north shore I nce found a rock which at first seemed to be a piece of pine tree stuck in a chunk of cement. Further examination revealed it to be fossilized wood embedded in river gravel and silt.

Very interesting lecture and I wasn’t interested in geology until I got in my 60s. I am appalled by many speakers and wonder if they are just nervous doing online presentations or if they speak the way they do in the classroom. It’s been a long time since I was in school, but if I presented something with all the pauses, stutters, ums, etc., my professors and teachers would have flunked me. So what has happened? Are the KZbin presentations a taste of what is being taught in classrooms today?,

Great Lecture. Thank you.

I studied geology in Los Angeles so never learned about New York geology. Almost as interesting as Washington glacial features.

thirty minutes previous glaciation features?

seventeen minutes in the diagram can be referred to as a cartoon
