Great Falls
	You can get a close look at the instruments the Captains used to record navigationn points. They used a chronometer, above, a quadrant, top right, and a sextant (not shown). A sign says the sextant was removed for " cleaning and maintenance." A model and explanation of the portage carts, right, gives you a good idea of the ingenuity of the Corps. They spent a month in the Great Falls area.
