- How would the fact that the Falls changed over time affect the descriptions explorers gave of the area?
- Why did the recession of the Falls stop in 1887?
- From looking at the map and the lines that show when the explorers reached the Falls, in what years would you expect to see an 'island' in the middle of the Falls?
