A boulder left behind by a retreating glacier is known as an erratic. A glacier is a moving river of ice and snow.
An example of a glacier moving a boulder would be when a large rock is picked up by a glacier as it flows downhill, and is transported along with the ice to a new location. This process, known as glacial plucking, occurs when the ice melts and the boulder is deposited on the ground.

The central part of the glacier moves fastest than its edges as it is thickest from the center.

Boulder Glacier is shrinking at an increasing rate, such that it will not be classified as a glacier soon (if not already). See the link below for repeat photos.

A large boulder left behind by a glacier is called a glacial erratic. These erratics are often significantly different from the surrounding rocks, providing clues about the glacier's movement and the rocks it passed over during its journey.
