In the state of New York, there are a series of 11 almost parallel and closely spaced lakes which are incredibly oblong. The reason for this is that each of these lakes completely formed during the last 2 million years, being owed to the action of ancient glaciers which once buried the landscape. This video will discuss how each of these lakes formed, such as Seneca Lake, and describe the difference between "U" and "V" shaped valleys.

Another great feature of the finger lake area is to the west of the lakes, Letchworth State Park. Known as the "Grand Canyon of the East" it must have been formed by a massive amount of water that formed a gorge approaching 600 feet deep. It is also one of only a hand full of rivers that flow from the south, to the north and empties into Lake Ontario. It was also recently voted the best State Park in America and has three major waterfalls. Great area to visit, especially in the fall. Amazing what water can form!

Aw man I love this, thanks so much! It’s wild seeing your channel covering our region, at first I thought I was dreaming it 😂 To add to this, there was an ancient finger lake, a HUGE one called Lake Iroquois, and I think the surviving relic of it is the Oneida Lake. I can’t remember if it spanned equivalent of two counties, but it slowly drained from not enough leftover glacial till to properly plug up the drainage channels.

@b.a.erlebacher1139 14 дней назад

Lake Ontario is the successor of Lake Iroquois. You can see old shorelines on both sides of the lake, with steep slopes between them, left from when the water level was higher, when the St. Lawrence was still blocked by the ice sheets and the Great Lakes drained through the Hudson Valley.😅

Did you know there was an early mini-rush for diamonds in Ithaca, NY (on Cayuga Lake)? Some veins identified as kimberlite were found, so people starting looking for diamonds.

@Dragrath1 14 дней назад

Interestingly due to how sediments infill bodies of water with no outlet Lakes have relatively short lifetimes on the order of tens to hundreds of thousands of years or less depending on their size eventually transitioning to various wetlands until they become filled in entirely. The only way to get older lakes is if you have some geological process removing sediment or expanding the lake basin as is the case with active rift lakes. Processes lakes can form from craters, calderas, landslide dams, lava dams, and various glacial processes. Thus unless you have or have had recent glaciation in an area natural lakes tend to be fairly rare so numerous lakes is a strong sign of glacial activity in general. Fun fact the Great lakes of North America are ancient basins which were excavated of weaker sedimentary fill rock layers by the glaciers. I think most of them owe their origin to Precambrian rift lakes when North America started to tear itself apart during the Mesoproterozoic only for that rift to ultimately fail. So in this sense these lakes are both ancient and very very young.

Interesting thought. But to take it a step further: How big & fast would a meteor have to be so that it triggered a volcanic eruption? Based on everything I know about historic meteors and how deep the deepest bore hole is and about the Chixculub crater, I guess that If a meteor was big enough to trigger a volcano, then it was big enough that the volcano does not matter anymore.

What did the edge of the Laurentide ice sheet look like? I've seen illustrations that show it as a massive ice wall, but this really doesn't make sense considering the more gradual tapering of some modern glaciers that terminate on land. But, then again, we don't have anything quite analogous to that boundary today. Either way, I imagine it would have been a spectacular sight!

This one hits close to home. My Paternal Grandmother's family had a Vineyard on Canandaigua Lake, in operation since the early 1800s. Blight, flooding and the Great Depression forced them off the land in the mid-1930s. They moved to another property, East of Niagara Falls NY -- the remnants of a Land Grant bestowed upon a Forebear for his Service in the Revolutionary War. This area also has a rather rich, Post Glacial, History. It was beneath a massive glacial Lake that stretched from Ohio, to the Mohawk Valley. [NOTE: On the formation of the Finger Lakes. Some contend that the weight of Glacial Ice (underestimated in depth) fractured -- or facilitated fracturing of the Crustal Plate. 🤷 Something to think about -- a pleasure in any measure.]

It's a common misconception that the glaciers moved south from the poles. The center of the ice sheet was in Hudson Bay and as it melted, it melted from north to south above that point. We have c14 dates that show this. The Siberian islands inside the artic circle were covered in forest. North of there and only 400 miles from the north pole; are islands that also had vegetation and megafauna. Photosynthesis isn't possible 6 months out the year there today. Pole wasn't where it us now.

Your geology is off. Mullins and Hinchey published seismic reflection profile investigations of the New York Finger Lakes in 1989 showing that they they actually have "V" shaped bedrock basins largely filled with "U" shaped sediment. Their great depths to as much as 1000 feet below sea level were eroded by subglacial water flows - not glaciation - although glaciers did carve and widen the upper shapes of the lakes. The Portage escarpment of limestone at the Southern ends of most of the lakes shows roughly how deep glaciation cut before the high pressure water flows eroded the shale North of that escarpment far deeper down to the level of the next lower sloping limestone level that limits the lake depths at their Northern ends. The water flows erupted at the Southern edge of the ice sheet and were too short lived to erode much of the limestone layers. The water flows give credence to a massive glacial melt off, which might be explained by extra-terrestrial impacts on the ice sheet.
