'Yosemite National Park': Massive Rockfall Leads To Hiking Trail Closure (VIDEO)

The incident of a rockfall caused a hiking trail to be closed at Yosemite National Park on March 31, the National Park Service said Monday.

No injuries were reported due to the rockfall, according to Yosemite National Park officials.

After 16,000 tons of rock fell 500 feet near Hetch Hetchy Reservoir, they slid down further towards a cliff and then dropped onto the ground below, Web Pro News reported.

About 400 feet for the Rancheria Falls Trail and some trees were crushed in the disaster.

"A rockfall in the Hetch Hetchy area of Yosemite National Park closes trail east of Wapama Falls. At approximately 1:30 p.m. on March 31, a large rockfall occurred from the cliff just east of Wapama Falls above the Hetch Hetchy reservoir," stated NPS.

"No visitors were injured. However, the trail was closed just east of the Wapama Creek footbridges for safety purposes, and due to boulders preventing access beyond Wapama Falls."

But through the trail that starts at the O'Shaughnessy Dam, hikers were still able to access Wapama Falls, according to WPN.

After the Rim fire caused all areas of Yosemite National Park to be affected last August, it was finally reopened last week.

"The Rim fire started in Stanislaus National Forest on Aug. 17, and burned approximately 255,000 acres, including 77,000 acres within Yosemite National Park," WPN reported. "The fire was not fully contained until late October, when the park celebrated its 123rd anniversary. The affected areas were closed until recently."

Hetch Hetchy hiking trails was included in the areas that officials said visitors should be cautioned off, with potential risks such as "hazardous trees, uneven ground, potential rockfall, and down and dead debris on trails."
