Also land rebound …but something here doesn’t make sense to me
From glaciers to volcanoes to earthquakes, witness the processes that have shaped the Puget Sound landscape.
When you first click on this video, it will appear that nothing is happening.
But look at the bottom left side of the video to see the year scrolling by.
Video by Burke Museum
Something here doesn’t make sense to me.
Notice that the ice extended south of Olympia about 17,000 years ago. Then, as the ice melted, Puget Sound waters extended almost to Olympia. Then, as the glaciers continued their retreat, the water also retreated.
Knowing that sea levels were 400 feet lower than today at the height of the last ice age, I thought we should see Puget Sound growing bigger as sea levels rose. Is the Burke Museum trying to tell us that the land rose (rebounded) by 400 feet?
I have visited the Burke Museum many times and have the utmost respect for them. Perhaps someone else can shed light on this? Did the land around Puget Sound actually rebound by the height of a 40-story building?
Thanks to Oly for this video
“Ice was 3000 feet deep here where I dwell,” says Oly.
