• On February 26, the Grand Canyon celebrates 100 years as a designated national park.
• The site is home to vast hiking trails, breathtaking views, and rare wildlife.
• Thrill-seeking visitors of the park can view the canyon from a glass skywalk that's located 4,000 feet above the ground.
• Other visitors might want to embark on a rafting journey through the Colorado River, which flows through the Grand Canyon.

The Grand Canyon has reached a major milestone this month.

On February 26, the Grand Canyon celebrates 100 years as a designated national park. There are tons of events scheduled throughout the Grand Canyon in the coming weeks to mark its centenary as a national treasure, but there's just as much to do and see at the park all year long.

The national treasure — which is not only spread across a swathe of Arizona, but also borders Utah and Nevada — has much to offer, from its breathtaking skywalk to its stunning nature views. These photos might make you want to visit.

According to scientists, the Grand Canyon has been around for millions of years.

Still, the exact age of the national park is debatable.

While some scientists believe that the park dates back six million years, other researchers feel there's enough evidence to prove that its actually been around for 70 million years.

In a study conducted by Nature Geoscience, researchers found that there's sound logic behind both of those numbers. Simply put, the middle of the Grand Canyon is likely older than its outer edges.

Its middle Hurricane segment was likely formed between 50 and 70 million years ago, while the nearby Eastern Grand Canyon was likely formed between 15 and 25 million years ago, according to Nature Geoscience.

However, the ends of the Grand Canyon are probably younger. Called the Marble Canyon and Westernmost Grand Canyon, these formations were likely carved from the Colorado River within the past five or six million years, the study found.

Much of the national park is filled with orange and red rocks.

While many of the formations look similar, there are actually multiple types of rock found throughout the park. According to the Grand Canyon's website, visitors can expect to find rocks such as limestone, siltstones, shale, and mudstones, among others.

Occasionally, heavy clouds will completely cover the landmark.

The phenomenon, called a cloud inversion, is pretty rare. It only occurs when "cold air is trapped in the canyon and topped by a layer of warm air," according to the Washington Post.

The view is breathtaking if you're lucky enough to see it in person.
