(NEXSTAR) — There are currently more than 400 National Park sites throughout the country, with at least one in every state, meaning there's a good chance you've been to at least one.

Even if you haven't visited some of the larger parks, like Yosemite, Yellowstone and the Grand Canyon, you're probably familiar with some of their more iconic features — El Capitan, Old Faithful, and the literal, expansive canyon, to name a few.

While these have been in the parks since before they were parks, visiting these sites didn't always look as it does today.

Take, for example, this view of Old Faithful in 1901. Changing attire styles means you likely won't see dress-clad women observing Old Faithful, especially at this proximity.

Here's what viewing Old Faithful is like today. Notice visitors, none of whom seem to be wearing a dress, are distanced from the geyser on a boardwalk — and using their phones to record the eruption.

Navigating in and around the parks has also changed immensely, thanks to technology. In the early 1900s, you could arrive at Yellowstone in a four-horsepower stagecoach, like those seen in the slideshow below. Later, cars would be available, of course. They were much smaller, though, narrow enough to navigate through the base of a massive redwood tree near Yosemite.
