Snowbanks are large accumulations of snow that can be found along roadsides, parking lots, and sidewalks. They can be formed by plowing or shoveling snow during the winter months, creating a barrier between the road and the sidewalk. Some synonyms for snowbanks include snowdrifts, snow mounds, and snow piles. These words all describe the same thing: a large accumulation of snow that is typically higher than a person's waist. Whether you're skiing down a snowbank or trying to navigate around one on your commute, these synonyms for snowbanks can help you better describe the winter wonderland around you.
