The central part of the glacier moves fastest than its edges as it is thickest from the center.
The fastest moving part of a glacier is typically the center of the glacier where it is flowing downhill and under the influence of gravity. This is known as the glacier's "zone of maximum flow" and can reach speeds of several feet to several tens of feet per day.
The center or axis of a glacier generally moves the fastest when the glacier is moving by internal plastic flow. This is due to the greater pressure and thickness of ice at the center, causing it to flow more readily than the slower moving edges and margins of the glacier.
The center of a valley glacier moves the fastest due to reduced friction from surrounding valley walls and terrain. This faster flow in the center can cause the glacier to stretch and crack, creating crevasses.
In the middle section. Just like in a flowing stream.
The world's fastest moving glaciers are found in Greenland and Antarctica. The Jakobshavn Glacier in Greenland is one of the fastest moving glaciers, reaching speeds of up to 150 feet per day. In Antarctica, glaciers like the Lambert Glacier have been recorded to move at speeds exceeding 16 feet per day.
The part of a glacier that moves fastest during internal plastic flow is typically the center or the upper layers. This is because the ice at the center experiences less friction from the valley walls compared to the ice near the edges, which is slowed down by contact with the substrate and surrounding terrain. Consequently, the flow is more pronounced in the central region, leading to higher velocities.
Glacier ice moves more quickly in the center of the glacier where there is less friction with the valley walls. It moves more slowly along the sides and bottom of the glacier where there is more friction with the rock and sediment beneath it.
Amazon Actually the fastest flowing river in the world is one that no one would ever suspect. I claim the Passiac River at Paterson NJ is hands down the fastest flowing river in the world during flood stage. The Great Falls of the Passaic River at Paterson NJ falls 77 ft into an extreme narrow gorge which at the head of the gorge the river channel is no more than 25-30 ft wide. It is at this point in the falls into which the greatest volume of river water plummets. At flood stage when there is many billions of gallons per day going over the falls, the combination of the velocity of the descending water crushing down onto the channel squeezes or puts pressure onto the water in the channel from above. This combined with a very narrow cross section causes the velocity in that short and small section of the river to easily flow some 70 mph. There is nothing like it anywhere in the country maybe the world. This is not a man made channel, it is natural, so the flow velocity during floods is the fastest naturally occurring flow (if you can call it flow, it literally shoots laterally out of the narrow section of gorge)

It is a valley glacier
No, a glacier canyon is not a real glacier. A glacier canyon is a canyon formed by the movement of a glacier over time, carving out the landscape as it flows.
