The trail to today's Geo Quiz is paved with gold.

We're looking for the name of an overland trail that links the Gulf of Alaska with the Pacific Ocean. There wasn't a lot of traffic on this trail a hundred years ago. Then, a couple of prospectors struck gold in an Alaskan riverbed.

" Two prospectors weathered over freeze-up and were prospecting during the winter months, they discovered gold on Christmas Day of 1908. Word didn't get out to the larger world until Fall 1909 because they were so remote and the first shipments of gold started to be carried 500 miles to Tidewater where they could be shipped to what we call up here the "outside".

Historian and trail administrator Kevin Keeler says it was America's last great gold rush. People came from all over the world to get in on the action.

So name this trail that became a gold superhighway.
