i’m pretty sure most people have seen this one. it’s an absolute beast and holds the title of largest open diamond mine in the world. at 525 metres deep with a top diameter of 1200 metres there’s even a no-fly zone above the hole due to a few helicopters being sucked in.

有看到下圖紅色箭頭指的是什麼嗎?是台"大"卡車!

a glory hole is used when a dam is at full capacity and water needs to be drained from the reservoir.
光榮(壯觀)之洞是用來幫滿水位的水壩排水的
his is the glory hole belonging to monticello dam in california and it’s the largest in the world, its size enabling it to consume 14′400 cubic feet of water every second.
the hole can be seen at the top left of the photo above. if you were to jump in for some reason your slightly damp body would shoot out near the bottom of the dam (below).
