River fog, ridge wind and Canton roofs
The river gives Collinsville fog and damp mornings that keep shaded roofs wet, so moss and lichen are normal on north slopes and slate holds algae. Above the village the ridges catch wind, and the open fields of Canton Center let it cross roofs unbroken. Elevation brings heavier snow than the valley towns east of Avon Mountain, and ice at the eaves is routine on the old village houses with uninsulated attics. Trees are everywhere, so valleys and gutters fill with debris each fall and branches come down in every ice storm.
