Update: 6:00 pm Monday
I spoke to the Narrow Island forest ranger and he said the fire had been extinguished. The Lake George Park Commission, the Bolton fire department, and the Hague fire department all responded. The fire was most likely started by some embers that were blown out of a fire pit by a strong south wind blowing today. In situations like this, they are concerned that the fire could get underground which makes extinguishing it much harder. All in all, we were quite fortunate that the smoke was seen and the fire was spotted early.
Shortly after noon today, a fire was spotted on Nobles Island off of Huletts. The ranger station on Narrow Island was alerted and responded quickly. Below are two pictures I took by boat. (Click image to see full-scale.)
