Pokhara, the second largest town of Nepal, has been built on massive debris deposits, which are associated with strong medieval earthquakes. Three quakes, in 1100, 1255 and 1344, with magnitudes of around Mw 8 triggered large-scale collapses, mass wasting and initiated the redistribution of material by catastrophic debris flows on the mountain range. An international team of scientists led by the University of Potsdam has discovered that these flows of gravel, rocks and sand have poured over a distance of more than 60 kilometers from the high mountain peaks of the Annapurna massif downstream.
Christoff Andermann from the GFZ German Research Centre for Geosciences in Potsdam participated in the study, published now in the Science magazine. "We have dated the lake sediments in the dammed tributary valleys using 14C radiocarbon. The measured ages of the sediment depositions coincide with the timing of documented large earthquakes in the region."

him Kali boulder on top of the sediment deposits near Pokhara in Nepal. The boulder is approx. 10m in diameter and weighs around 300kg. The timing of deposition of this boulder has been dated in this study and coincides with the timing of a large earthquake in 1681 in Nepal.
I’ll bet that rock weighs more than 661 lb.s but it sure makes a nice rock garden. No other rocks needed.
Yup and it’s at least 14+ Meters in dia.
Yeah, you might be right. That’s a little harder to tell from the pic but it might go 46 ft rather than 32. It’s a beaut of a rock in any case. Hate to have it land on my house.
To be fair the pic caption was an editing error.
The article estimates its weight at 300 tons.
I don’t think I’d buy any real estate in Nepal. If a few thousand cubic meters of your uphill neighbors property ended up on your plot, who owns the surface??
Tiny little brown gal worked at the gas station across the street a few years back. Hope she/hers there are OK.
Oops, yes, she was Nepalese...
I think Climate Change does that. That’s what a scientist said in another article about a great big rock last week.
E-Z-Care Rock Garden. Rake once and forget.
Thanks JimSEA.
300 Kg?
Prolly a lot more than that.
45 tons more like it.
so, at roughly r=7 m= roughly 21' the volume becomes 38,772 cf
at say 150 #/cf the weight becomes 38,772 * 150 = 5,815,908 Pounds
So, the rough approximate weight is in the neighborhood of 5.8 million pounds or 2,900 tons
Whoever is still breathing! ;-)
Thanks ct.
