It is hard to imagine that Yosemite National Park in California is only 60 miles from San Francisco — where it never ever snows and rarely gets below 32 F in the dead of winter.This is an incredible video! It only happens in March and April. I have never seen a creek come to a complete stop like this before and start up again someplace else.
It’s like a lava flow.
