In the middle, contained in a giant soup-bowl-shaped spatter cone, was a stunning sight: a lake of lava.

中间是一块巨大的汤碗形寄生熔岩锥，壮观的岩浆湖就被盛放在巨碗之中。

Standing on the crater floor, he couldn't see the lake itself, which was above him within the cone of cooled lava.

站在火山口的地表上，他根本看不到岩浆湖，因为位于锥形冷却熔岩的岩浆湖在他的视线之上。

The hardened lava extends some 4 miles (6 kilometers) from the cinder cone, and is about 100 feet (30 meters) thick.

变硬的火山岩一直延伸到离火山灰锥4英里（6公里）远的地方，厚达100英尺（30米）。

And dead ahead is the gaping cone of Vesuvius, long tongues of lava from the last eruption (1944) visible even from here.
