Every spring, travelers come to Newfoundland from around the world to see the icebergs drifting southward. As big as a city block covered in office towers, or as small as a grand piano, these mountains of freshwater ice began thousands of years ago when snow fell on Greenland. Science writer Lawrence Jackson unravels the mysteries of icebergs for children in this clearly-written book, illustrated with remarkable watercolours and paintings on silk by Newfoundland artist Diana Dabinett.
