For today's Geo Quiz -- we head to Yukon. 100 years ago a Canadian geologist mapped the area near where the Klondike and Yukon Rivers meet.

His maps came in handy a few years later during the Klondike Gold Rush. Thousands of fortune seekers headed north to Yukon. But it's the city that was at the heart of all that gold fever we're after. It adopted the name of that Canadian geologist.

These days, thousands of tourists visit each year to catch a glimpse of the midnight sun, pan for gold, or gamble at Diamond Tooth Gertie's.
