waterfall

Sometimes the river flow is interrupted by a jump: this is a cascade. The water falls down abruptly hitting the ground and splashing everywhere, fine drops are sprayed in the air making it fog, a deep rumble is heard from very far away. At the bottom of the waterfall there is a sort of big lake: to take a bath here could be dangerous because the water strength drags down also sea rocks. There are images of waterfalls taken in the Hawaii and in New Zealand.
