Document Summary

Scientist says city must plan for an escarpment that will always be falling down". The niagara escarpment is falling down, hamilton has closed parts for maintenance, slope repairs or rock scaling to try and help (adjusting budget accordingly). Winters with fluctuating freezes and thaws have exacerbated rock movement. Dr. eyles (glacial sedimentologist from mac) says hamilton needs to get used to rock falls the escarpment is still forming. Escarpment is millions of years into its process of solid cap rocks on top of weaker shale rock called mudstone. The eroding mudstone base affects the integrity of the cap rocks the fractures of the cap rocks fill with water, and when the water freezes, the cap rocks become further compromised, eventually breaking. The escarpment is moving down towards london. Behind the canadian shield" (this literally has so much info ughhhsdfjhd) Harold innis famously claimed that canada emerged not in spite of geography but because of it.
