Stone Wall Secrets

What can rocks in old stone walls tell us about how the earth’s crust was shaped, melted by volcanoes, carved by glaciers, and weathered by the elements? And what can they tell us about earlier people on the land? As Adam and his grandfather work to repair the family farm’s old stone walls, Adam learns how fascinating geology can be, and how a landscape provides clues to the past.
