Also not mentioned are the Elongated Lakes as evidence of the Cosmic catastrophe.
All oriented NW/SE with the skinny end to the NW. like something came from that direction a gouged the trench. The suggestion is that Earth was hit with a great hail of cosmic debris
North Carolina also has thousands of lakes, tho not as long, they are likewise oriented in the same direction as the ones in Alaska.
"Many explanations have been advanced for the origin and orientation of the Carolina Bay Lakes and swampy depressions (the 'Carolina Bays"), including meteor impact and limestone dissolution (Melton and Schriever, 1933; Johnson, 1942; Prouty, 1952; Livingstone, 1954; Schriever, 1956; Thom, 1970), but at present wind and wave action are most widely considered to be responsible for the initiation and shaping of the Bays (Kaczorowski, 1977)."
Lakes come in all sizes and shapes, but they're rarely oriented in the same direction," said Jon Pelletier, an assistant professor of geosciences at The University of Arizona in Tucson.
Now Pelletier has proposed a new explanation for the orientation, shape and speed of growth of oriented thaw lakes. The lakes' unusual characteristics result from seasonal slumping of the banks when the permafrost thaws abruptly, he said. The lakes grow when rapid warming melts a lake's frozen bank, and the soggy soil loses its strength and slides into the water. Such lakes are found in the permafrost zone in Alaska, northern Canada and northern Russia.
Previous explanations for the water bodies' shape and orientation invoked wind-driven lake circulation and erosion by waves.
"We knew about the thaw slumping, but we didn't know it had to do with the shape of the lakes," Pelletier said. His new mathematical model describing the formation of oriented lakes by thaw slumping will be published on June 30 in the Journal of Geophysical Research.
Pelletier's interest in oriented lakes was sparked by teaching geomorphology, the study of landforms. "'Oriented lakes' is one of the classic subjects that comes up in class. There was a textbook explanation that I didn't find convincing, so I decided to tinker around with alternative models."
Pelletier does his tinkering by plugging mathematical equations into a computer.
"The computer allows you to put the processes into the model and say, 'If the winds blow this way, what kind of a lake would you expect to see?' or 'If it's from thaw, what would we expect to see?' You do still need to go and see, do the winds blow this way or does the thaw happen that way."
On Alaska's North Slope, the prevailing winds blow perpendicular to the long axes of the lakes. According to the traditional explanation, such winds set up currents within the lakes that erode the banks, particularly at the lakes' ends. Such currents would erode coarse-grained, sandy soils faster than fine-grained clay soils.
According to Pelletier, one key ingredient for oriented thaw lakes is permafrost – the special mixture of soil and ice that forms the surface of the land in the Far North. On the north coast of Alaska and at similar latitudes throughout the world, the top, or active, layer of the permafrost melts at some point in the summer and refreezes again in the fall.
“What users are seeing is an artefact of the data collection process.… Bathymetric (or sea floor terrain) data is often collected from boats using sonar to take measurements of the sea floor.… The lines reflect the path of the boat as it gathers the data. The fact that there are blank spots between each of these lines is a sign of how little we really know about the world’s oceans.”
"The image reflects a mixture of bathymetric data from sonar and satellite altimetry, which provides an estimate of the ocean floor topography based on wave height."
"The intersection of these two data sets, which don't align perfectly, is what produces the appearance of a street grid. Similar grid lines can be found in other parts of the ocean where the sea floor has yet to be completely mapped, such as near Hawaii."

Sorry Amenesis, The wind is not a good explanation. They are grasping at straws there.
What is so hard to understand about cosmic debris being the cause?
