This graph shows the average times that the fires in Arrowtown were lit during the month of June. As you can see, most of the houses would likely have their fire on in the morning, but will let it die out as the day goes on. At 3:00pm the residents seem to relight their fire and keep stacking logs inside, soaring above the base temperature 14o and into the 40o - 50os before leaving the fire to die out at its peak at 8:00pm.
