River damp and winter cold in Sprague
Sprague's villages sit low along the river, where damp air collects and north-facing roofs stay wet into the morning, so moss and algae are common on the mill houses. The farm roads on the ridges above are more open, and wind reaches those roofs with little to break it, lifting shingles on the exposed slope. Winters here are inland winters, with snow that lingers and freeze-thaw cycling that builds ice at the eaves on houses with cold attics. Tree cover on the wooded lots drops branches and leaves into valleys and keeps the shaded side of the roof from drying.
