We're taking a walk on the beach for today's Geo Quiz.

The beach we have in mind is in a county at the southwest tip of England. The coastline there is known for its impressive rocky cliffs and moors. But there are sandy beaches, too.

Isles of Scilly

They're exposed to steady winds that blow in from the Atlantic. That may explain why driftwood and all kinds of other stuff regularly washes up on these shores. We'll tell you about a suspicious package that washed up recently that British police are investigating.

It may have floated all the way across the Atlantic, past the Isles of Scilly and up onto a local beach. More about that suspicious parcel in a few minutes. First, try and name the county that sits at England's south-western tip.
