Stella-Jonescontrolled-burning-in-progress plans to burn the slash piles on Boulder this fall sometime between now and Christmas.  Given the burning rules around venting they will not know in advance when exactly this will be happening.  They often only have about 1 hour of advance notice of an appropriate burning window.  If they are burning, please stay well away from their operations to allow them to perform their work safely and to ensure your own safety.
