Who were the culverts?

The Culverts were a group of influential figures in the 19th-century American art scene, particularly known for their contributions to landscape painting. They were part of a movement that emphasized the beauty of nature and often depicted idyllic rural scenes. Their work played a significant role in shaping American artistic identity during that period. However, it's worth noting that the term "culverts" may not specifically refer to a well-documented group in art history, and you might be thinking of another term or name.
