It's called an erratic. See http://en.wikipedia.org/wiki/Glacial_erratic.
This isolated boulder left behind by a glacier is called a glacial erratic. Glacial erratics are large rocks that are carried by glaciers and deposited in a different location when the glacier melts. They can vary in size from small pebbles to massive boulders and are often composed of different rock types than the surrounding landscape.

The soil and rocks left behind by a glacier are called moraine. Moraines can be classified as lateral, medial, or terminal, depending on where they are deposited in relation to the glacier. These deposits play a vital role in shaping the landscape and providing insights into glacial history.
The material left behind by a retreating glacier, including boulders, sand, clay, and silt, is known as moraine.
A moraine is a low ridge of rocks, sand, and soil that is deposited by a glacier as it advances and retreats. It can be found at the edges or terminus of a glacier, marking the furthest extent of the glacier's advance.

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.
A boulder left behind by a retreating glacier is known as an erratic. A glacier is a moving river of ice and snow.
An isolated large boulder (known as an 'erratic boulder') standing in the open, was left there by a glacier, after the ice retreated at the end of an ice age.. They are known as an 'erratic'.
