"You are going to be working in some really nasty mud because this isn't your ordinary mud. This is the kind of mud that comes of the burn scar. So whatever sludge was in the river brought more sludge down from the fire. It's pretty nasty stuff," said Fortune.

If you're interested in helping out, just show up at City Hall on Manitou Avenue to register. Officials say they work from 8 a.m. to 3 p.m. If you can't shovel, Fortune said there is plenty of other work like helping with records and organizing volunteers.
