"Next stop is the early 19th Century. Lewis and Clark should have crossed the Rockies by now, but instead, they seem to be stopped in their tracks! Better see if you can get them moving again.

Once again, you'll be exploring unknown territory, so I'll send Rock Solid as your Good Guide. Good luck...and watch out for rattlesnakes." -- The Chief

"Congratulations once again! You re-busted the Baron, learned to speak with your hands, and led Lewis and Clark to the Columbia River!

Thanks to you, the wildest part of the Western U.S. is well on its way to being tamed. Great going!

But there's more lawlessness in the very near future, Time Inspector. Can you move on to a new case right away?" -- The Chief
