so much of what we think really is permanent is just chance natural occurence. i read that the san fran bay was formed when an ice dam at benicia broke and flooded the what is now the bay, and that the bay will be gone in 1,000 years. yet, so much time and effort is spent on “preserving the bay” like it was somehow meant to be some permanent thing.
I think we need to restore that old lake, since it was obviously a ‘good thing’ to have for the fish. / sarc
Many ancient ports ( Roman and others thousands of years ago ) have silted up and went away .
The Colorado River [ and other rivers , likely ] has had many dams ( thru landslides or volcanic intrusions ) and resulting lakes...which , over time, had the expected results ( went back to a river ).
A kindred spirit! The Earth is constantly changing due to forces far beyond real human control. We are such arrogant, short-sighted little creatures! Any first-year geology student has a far better understanding of humanity's place on this globe than 99% of the people dwelling on its surface and at the mercy of its many moods. Stop Plate Tectonics!
