Among nature’s most beautiful wonders, waterfalls come in all shapes and sizes, from serene cascades to mighty cataracts. The U.S. Postal Service celebrates the variety and beauty of American waterfalls with 12 new stamps.

Framing the stamps is selvage that again features David B. Vernon’s LaSalle Canyon image.

A waterfall is part of a river or stream where its flow pours over a near vertical rocky ledge or cliff of some height before coming in contact with rocks or a pool below. Waterfalls can be classified by volume, height, and width; another popular method is by type, based on the way the water actually falls. One of the most familiar types is the plunge, where the stream falls vertically without touching the underlying cliff face; sometimes there are caverns behind the falls carved by earlier erosion. As the name suggests, a fan waterfall resembles the shape of a fan as the flow spreads down the rocks. Other types include the cascade, which breaks into smaller falls as the water descends over a slope of rocks and boulders, and the cataract, where large amounts of fast-moving water plummet over a cliff to create a waterfall of great size and power.

Each of the waterfalls is unique, but what they all have in common is the way they kindle positive emotions, such as the serenity instilled by a gentle cascade or the awe inspired by an immense cataract.

Art director Greg Breeding designed the stamps and pane with existing photographs.
