Beam Specs

Real nice day at the springs today. Had a chance to go up and check out that big stick I was talking about with my trusty tape measure. Its 10 inches by 18 inches by 41 feet. I'm wondering how much this thing weighs? I suppose it could be calculated, any body got any idea? This big hog is a lanimated beam and is solid as a rock. 18 inches is plenty wide for a walkway across the stream and this pig is flat and smooth! Gettin this huge puppy into a good spot below the hotsprings is the only problem. Hey, the next time any of you go down to the springs with 100 of you super strong friends maybe you could talk them into goin up there and carrying this big boy down to the springs and set it into position in a good spot. I'll take care of the rest :-)
