the water level rose on the coasts a lot. 50 feet? 100 feet? 150 feet?

400-700 feet
I’d really like to see more maps of what the coastline looked like during the ice age, during different parts of the ice age, etc.
I’ve heard that there are underwater structures 2,200 feet below sea level, I believe off the coast of Cuba. That is hard to explain by the end of the ice age. Most of the ancient underwater structures seem to be sitting where it would have been dry during the ice age.
