A huge boulder carried by a glacier is called a glacial erratic. These erratics can be transported significant distances from their place of origin and deposited in areas with different geology.

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.
Moraine is the word for rocks and boulders carried along by a glacier and then left behind.
