+joc Posted March 17, 2019 #9 Share Posted March 17, 2019 I can estimate it! The rock is basically already marked in quarters by the wood and ropes. Each quarter is about 4000lbs...there are 4 quarters...16,000lbs. I'm basing that on the weight of the bottom rock of the waterfall I built with my koi pond. It weighed about 2000lbs. So, a good estimate I think would be between 15,000 and 20,000 pounds. 3 1 Link to comment Share on other sites More sharing options...
+joc Posted March 17, 2019 #10 Share Posted March 17, 2019 Actually, looking at all the pics....the width of the bottom rock I used is about 2/3 the width of that rock...so increase the overall weight by 1/3....probably somewhere in the 25,000 pound range. 2 Link to comment Share on other sites More sharing options...
+joc Posted March 17, 2019 #11 Share Posted March 17, 2019 Calculating the weight of monoliths In the cases of the smaller monoliths it may be possible to weigh them. However, in most cases the monoliths were too large or they may have been part of an ancient structure so this method could not be used. The weight of a stone can be calculated by multiplying its volume and density. The density of most stones is between two and three tons per cubic meter. Basalt weighs about 2.8 to 3.0 tons per cubic meter; granite averages about 2.75 metric tons per cubic meter; limestone, 2.7 metric tons per cubic meter; sandstone or marble, 2.5 tons per cubic meter.[1][2][3][4][5] Some softer stones may be lighter than 2 tons per cubic meter, like volcanic tuff, which weighs about 1.9 tons per cubic meter.[6][7] Since the density of most of these stones fluctuates it is necessary to know the source for the stone and volume to obtain accurate measurements.[8][9] https://en.wikipedia.org/wiki/List_of_largest_monoliths 2 2 Link to comment Share on other sites More sharing options...

Hey did I say I was going to spoon fed you the answers? Big grey rock on sled, probably wet too, pull by people who I estimate are 5'4" tall and weigh on average 128 lbs (1.62 meters and 58 kilograms).....okay, ok I made that up....

There a few papers that estimate 30 tonnes plus. Example below. https://www.academia.edu/3359825/Megalithic_Tombs_Power_and_Social_Relations_in_West_Sumba_Indonesia That is a very specific estimation you have given.
