So, the picture of your burn pile, coupled with the big loader arriving, has sparked story time:
I contracted with old Frank (74 yo) per my neighbors recommendation to build my road and clear my building site out of the freshly logged 10 acres I purchased. He was eager for the extra business as he had just had the engine in his Pettibone loader rebuilt.
Frank was a one man operation. He brought the big loader out, then the smaller one. He would commute in his old Ford pickup with the dog, 2 chainsaws and a shotgun.
It didn't take long at all before I had a nice circular road built of concrete waste with crusher run on top of it in the low spots and a humongous pile of stumps and **** trees piled 10' tall along the backside of the build site. We're talking 10' tall, 15' deep and 100 yards long.
Franks parting words were: " When the snow gets deep, light 'er off."
Well, I planned for just that. My old travel trailer was on site with a propane furnace and my Ramcharger was good to 15" deep. One late December day when conditions were right on the weekend, it commenced. I didn't want the whole 100' yards to go, it narrowed a bit at 75 yards so I piled shoveled snow in a big pile at that spot.
5 gallons of gas, a match and HOLY ****. Once that thing got going, flames were 30'-40' high and even on a relatively calm day, ash was drifting onto the neighbors property 300' away. My pile of snow at the neck didn't stand a chance, fire was eating through the bottom and heat was melting it in a hurry.
That last 30some feet of pile was the area closest to the neighbor, so I was running all over the site hauling snow to toss on that spot, I did NOT want it burning. I just barely managed to stop the fire from eating through.
Crisis averted. Time to settle in a spend an evening in the winter woods. All was well until about 3:30 in the morning. The durn furnace is sputtering, then as I watched: Whoosh! The burner ignited and a flame shot out 6". Yikes! the regulator isn't working right. Shut it down. Now what? Sleeping in the Ramcharger with the motor running is a whole 'nother kind of dangerous, it's a carburetor.
Well, the glow is looking pretty tame, winds are calm, it's actually foggy out. Drove home the 70 miles.
3 days later, I had to be out that way for work, I'll check the site. Wow. It was still glowing away deep down under. If Frank hadn't left a decent buffer to the rest of the woods, it would have eaten along tree roots and kept burning like an underground coalfire forever. Thanks Frank! RIP.
