Travelers can get up close and personal with many of the world's natural wonders, such as hiking along a wooded trail to Crabtree Falls in North Carolina, USA, or standing on the edge of Yellowstone Falls to see the magnificent view in the distance.

Not only do tourists marvel at these waterfalls, but some filmmakers also have a fondness for them. But only a lucky few get to see the spectacular waterfalls around the world up close and personal with a sense of awe. These falls are high and wide, and some even span different countries.

Oregon, USA, is located north of California with beautiful mountains and water. Both the mountains and the water certainly have waterfalls.

Silver Falls is a state park in Oregon. It is 25 miles from Salem, the capital of Oregon. It is famous for its pristine forests, cascading waterfalls and exotic flowers, and fresh air.

"Silver Falls is the largest state park in Oregon, covering 50,000 acres. There are ten different waterfalls in the park, and although they are not particularly well known in the United States, it is rare to find them all in one park.

South Falls is the most visited of the 10 different waterfalls in Silver Falls State Park in Oregon, USA. Visitors can enter a natural cave along a trail from the back of South Falls.

The majestic beauty and thundering majesty of the waterfall that cascades straight down are stunning. It is known as one of the most spectacular natural sights on earth.

At some shores where rivers flow into the ocean, the rivers are "shortened" because of the violent waves that often lap the shore, forcing them to "retreat". If the coast is destroyed fairly quickly, then the original river bottom above the sea will also be "inverted" on the coast, and the river at the sea will form a waterfall.

If the river's water volume is very large, it will form a spectacular waterfall, the sound of rumbling water can reach thousands of meters away, and the splash of water in the air to form a large white mist, a very spectacular scene. In some mountainous areas, streams or springs can also form waterfalls, although the amount of water is not large, the water drops from high cliffs falling, such as silk, also have a unique sense of beauty.

Waterfalls are formed by the internal and external forces of the earth. During the river's time, a waterfall is a temporary feature that eventually disappears due to the impact of the waterfall's drop, the volume of water, the type and structure of the rock, and several other factors.

But where there is a waterfall, the river always erodes in the upstream direction, trying to smooth out the high places and make the river level. Dripping water can also penetrate rocks, and the erosive power of water is so strong that it can disintegrate rock formations that are incredibly hard.

The faster the river flows, the stronger the erosive force on the river and its banks.

The river continues to disintegrate the upper part of the waterfall, allowing the rock layer to break and fall, so the location of the waterfall gradually retreats in the upstream direction, and the drop of the waterfall is reduced.

In some cases, the position of the waterfall recedes in an upstream direction as the cliff or steep canyon is scoured by the current, while in other cases, this erosion tends to cut deeply downward and slash the entire section of the river containing the waterfall.

Over time, with either or both of these factors at work, the waterfall will gradually disappear.
