Some revellers are filtering out of the site and through the Nevada desert before its official end.
Around 70,000 attendees were trapped on the site over the weekend in the midst of a heavy and unexpected storm.
The entrance was closed and fans were urged to conserve water, food and fuel.
The festival is ploughing on with plans to burn its iconic effigy later on Monday, 4 September, after it was postponed due to the rain and flooding.
“The Man burn will not happen tonight, Sunday, it is now scheduled for Monday 9/4, at 9pm,” the festival said in an update yesterday.
