1. Pure Springs Along the Missouri River Marker
Inscription.  Over 150 million gallons of water flow from Giant Springs everyday and cascade into the Missouri River.

The springs occur where cracks in the rocks above the Madison Limestone allow water to leak upward to the land surface. It is similar to a leak in a hose where the water, under pressure, will exit upwards through the overlying opening.

Waters of the spring have been tested and found to be very pure. However, it is not advisable to drink the water directly from the springs because birds and other animals live in and use the water.

As you visit the spring today, you can see that William Clark's description is still true over 200 years later:
“…largest fountain or Spring I have ever Saw, and doubt if it is not the largest in America Known, this water boils up from under th rocks near the edge of the river and falls imediately into the river 8 feets and keeps its Colour for a mile which is emencely Clear and of a bluish Cast…”
William Clark

Also see . . .  Lewis and Clark: Giant Springs. On 18 June 1805, after measuring the "second great Cataract" —the "handsom Fall" — Clark and his five men "proceeded on up the river a little more than a mile to the largest fountain or Spring I ever Saw, and doubt if it is not the largest in American Known." The "emencely Clear" water, which seemed to him "of a bluish Cast," could be seen distinctly for half a mile down the river, which three weeks later he later measured at 270 yards in width.
