Holidaymakers film 200ft glacier plunging into water as their tourist boat passes by

Terrified tourists filmed the moment a massive glacier plunged into the water as their boat passed by Tracy Arm Fjord in Alaska.

The glacier crumbled with such force that it caused a huge wave that rocked the boat and chunks of ice were sent flying through the air.

It is thought that one woman broke her leg in the incident, when the tourist boat was shoved by the impact of the ice on the water.

In the video above you can hear the terrified screams of the passengers on the tourist boat and see the blocks of ice hitting the water just metres from them.
