These huge rocks were probably deposited by Ice Age floods, either pushed here by an immense current of the Missoula Floods or floated here in that same water, embedded in chunks of ice from a glacial lobe in Montana. Another theory is that they were deposited by the glacier that created the Withrow Moraine, though this area seems to lie outside the boundary of the moraine (see map drawing in the link below).
