Pictures show little to no visibility and several feet of snow covering Yosemite, making it nearly impossible for visitors to walk or drive through.
The park was expected to open on March 1 after being closed in late February.

"Park crews are working to restore critical services so visitors can safely return," Yosemite National Park's Twitter said on Wednesday. "There is no estimated date for reopening."
Yosemite also closed on February 5, 2019, due to similar winter conditions. The park's roads were unnavigable due to heavy snowfall.
The closure comes as Californians across the state struggle with the unusually snowy weather. Governor Gavin Newsom declared a state of emergency on Wednesday amid widespread power outages affecting tens of thousands of residents.
