Crevasses
The cracks in an ice glacier are called crevasses. They form due to the movement of the glacier over uneven terrain, causing the ice to fracture and crack. Crevasses can be dangerous to climbers and hikers as they can be deep and difficult to see.
The st lawrence river is about 40m (132 ft) deep on average, and its maximum depth is about 205 ft deep.
Crevasses in glaciers are limited to around 50 meters deep because of the way ice behaves under pressure. Deeper crevasses would experience increased pressure from the weight of the ice above, causing the ice to deform and close up the crack. This limit helps maintain the structural integrity of the glacier.
Crevasses are limited to 50 meters depth due to the ice's ability to deform under pressure. At greater depths, the weight of the ice causes the glacier to flow rather than crack. Instead of deepening, the ice will undergo plastic deformation to accommodate the stress.
In the deep jungle mango trees, fighting for light, commonly reach 40m (120 feet) high, in plantations about 15m (45 feet).
Crevasses are dangerous because they can be deep and hidden under thin snow bridges, making them difficult to spot. If a person were to fall into a crevasse, it can be challenging to escape due to the steep icy walls and the risk of snow collapsing in on them. Additionally, crevasses are often found in glaciated areas where rescue can be difficult and time-consuming.
To calculate the volume of a rectangular prism, you multiply the length, width, and height. 40m × 40m × 60m = 96, 000 m3.
An innumerable number of snow bridges hide deep crevasses, otherwise, there are no man-made bridges on the continent -- nor are there any roads.

Crevasses form on the surface of glaciers due to differential movement of the ice. As glaciers flow over uneven terrain, areas of tension and compression develop. These areas of tension can create crevasses, which are deep cracks in the ice caused by the glacier's movement.
Chasm!! :D
