So this is what 180 bales of marijuana looks like.
CBS 2 News reports that the stash was discovered this past Sunday floating aimlessly in the waters near Dana Point, California.

All in all, the stash contained at least 8,000 pounds of weed with an estimated the street value of over $4 million! And Border Patrol, the Coast Guard as well as local authorities are still dumbfounded in trying to identify their source:
"At other events, they've dumped the bales to get rid of weight if they're being chased," said Border Patrol spokesman Michael Jimenez referring to drug runners. "Generally in these cases we're aware they're being dumped. What's more unusual is that the bales were floating with no boat in sight."
