You haven't seen Yosemite like this: stunning time-lapse video

Yosemite HD II from Project Yosemite on Vimeo.

The stunning span of mountains, glaciers, waterfalls and valleys within California's Yosemite National Park naturally seem to inspire photographers. (Ansel Adams, anyone?)

Two filmmakers, Colin Delehanty, 27, and Sheldon Neill, 22, joined forces to make a time-lapse video of the park. The two met through the video-sharing website Vimeo.

The production, Yosemite HD II, was a serious commitment: Over 10 months for a total of 45 days, the two traveled some 200 plus miles of lesser-traveled backcountry as well as around recognizable landmarks, all while loaded down with 70-pound backpacks filled with camera equipment and hiking gear — and a lot of patience.

The work resulted in an eye-popping video. Whether you're a regular to the park or have never visited, the film is a must-see.

"Climbing in Yosemite inspired me to capture the park from a unique perspective," said Delehanty, who works as a photographer. Neill, who works at a special-effects company, said that he was taken by Yosemite's "grandeur and massive vistas."

Neill added that it was one of those places that "changes your life. I've always wanted to document my backpacking trips too. Time-lapse became a medium for that."

The experience was meaningful to the two.

"I've learned more than I can describe," Neill told Yahoo. "I discovered places within the park very few people ever go."

Delehanty recommends that visitors see the waterfalls in Yosemite Valley and travel to the park during winter. "I think Yosemite is most beautiful after getting a fresh coat of snow," he said.

Neill has his own favorites. "Tuolumne or anywhere in the Cathedral Range. It's magical back there."

In honor of National Park Week, entrance to the park is free April 19 and 20. In the meantime, you can enjoy the magic of Delehanty and Neill’s time-lapse video.
