In the world I am designing, I want to have a bay with a tight bottleneck, filled with salt water from the ocean. You can think of the bay as river shaped. To avoid creating a "C" shaped island I want to have the bay to end at the base of a volcano where the heat will evaporate the water and leave behind a salt flat.
I want to have the volcano go through cycles of activity and inactivity to allow the area to become dry (during a time of high volcanic activity) and become something like the Dead Sea (during a time of low volcanic activity).
- Is this even feasible?
- How long would the cycles be (months, years, decades)?
- What kind of life could I expect nearby (I am mainly worried about the plant life. I am working on an animal that can survive this harsh environment)?
