Here is a nighttime shot of the Harris Fire. |
This is an image of the peat bog fire that smoldered for weeks in the barka slough after the Harris Fire burned into that area.About Peat bog firesPeat is the semi-decomposed remains of plant matter. Sometimes in cool low-oxygen boggy areas the plant remains will not fully decompose. Over centuries this can lead to layers of semi-decomposed plant matter called peat. On occasion a nearby wildfire can burn into the boogy and moist area. This will lead to a slow smoldering that can continue for months and years. These can be extremely hard to extinguish due to the difficulty of maneuvering trucks and equipment through the marshy environmentally unique areas. A solution was utilized at Vandenberg Air Force Base in late 2000 after the Harris Fire burned into a 365 acre peat bog called Barka Slough. This peat bog still had eighty acres of bog smoldering as of this writing (November 2000, two months after it started). This fire is particularly hard to put out due to the fact that the soils in the bog is composed of three feet of clay on top of the four to seven feet of clay and peat mixed that is smoldering. Putting a regular amount of water on such a fire is not productive. The water must soak through the three feet of clay to get to the clay/peat layer that is burning. So the water must be put on for a long long time. In this case the remedy to extinguish the fire is twenty oscillating sprinklers with over 2,000 yards of six inch irrigation pipe. The wells are on nearly constantly spaying water across scores of acres at a time. This system will deliver 3,000 gallons of water a minute, and they have pumped over 150 million gallons of water onto the subterranean fires.
Here we see an image of the Harris Fire, seen from miles away, with huge columns of smoke wafting thousands of feet into the air. |
