How long does it take for a glacier to carry a erratic?

The time it takes for a glacier to transport a glacial erratic can vary significantly, depending on factors like the glacier's movement speed, the distance the erratic needs to travel, and environmental conditions. Glaciers can move at rates ranging from a few centimeters to several meters per day. Typically, this means that an erratic could be carried over distances of several kilometers in a matter of days to weeks, but the entire process of transport and eventual deposition can span years to centuries as glaciers advance and retreat.
