Two issues ago I started a brief review about the geologically hazardous position of Naples, Italy, snuggled between the volcanically active area of Campi Flegrei in the west and the Somma-Vesuvius volcanic complex to the east.
One of the surprising things of the "Ice Age" is that about 10,000 to 12,000 years ago, a large embayment of the Atlantic Ocean extended up the St. Lawrence Valley into southern Quebec and eastern Ontario. The seashore extended across from the Lake Ontario basin near Kingston northeastward near Carleton Place to the Ottawa Valley as far as Pembroke. All of Ontario east of that shoreline, including Ottawa, and much of the St. Lawrence Valley of Quebec was flooded by sea water to depths as great as 100m (Fig. 1).
A University of Waterloo Earth Sciences undergraduate student received the Wood Bursary for the second year in a row.

Deep under a mountain range I was a part of a great mass of granite. I started my second rock cycle as molten magma, which gradually cooled over millions of years. When the mountains of which I was part of were eroded by wind and rain, my tiny particles became mud and sand. My quartz crystals were ground down and formed sand. This sand was just like the sand you play with on the beach in the summer.
