A boulder left behind by a retreating glacier is known as an erratic. A glacier is a moving river of ice and snow.

Moraine is the word for rocks and boulders carried along by a glacier and then left behind.
This is likely referring to till, which is a mixture of unsorted materials (rock, sand, and silt) left behind by a retreating glacier. Till layers can vary in thickness and composition, and they are often seen in areas where glaciers have once existed.
A boulder left behind by a glacier and deposited among rocks of a different type is called a "glacial erratic." These boulders are typically composed of rock material that differs from the surrounding geology, having been transported by the glacier over long distances before being deposited as the ice melts. Glacial erratics provide important clues about past glacial movements and the geological history of an area.
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.

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 material left behind by a retreating glacier, including boulders, sand, clay, and silt, is known as moraine.
