Roar of Waterfall, Rush of Rapids
The place where we encamped last night needed no embellishments to render it romantic in the highest degree . . . a few yards below us a beautiful cascade of fine spring water, pouring down from a high precipice about one hundred feet high. On our left was the Mississippi hurrying through its channel with great velocity, and . . . above us . . . was the majestic cataract of the Falls of St. Anthony. The murmuring of the cascade, the roaring of the river, and the thunder of the cataract, all contributed to make the scene the most interesting and magnificent of any I ever before witnessed.The waterfall that created the river gorge we see today was the remnant of a much greater falls that once roared beside the current site of downtown St. Paul, and was the precursor of modern day St. Anthony Falls in Minneapolis. Year after year the waterfall cut a path through layers of sedimentary bedrock. As soft, underlying sandstone eroded beneath the force of falling water, the limestone caprock was undermined, and chunk after chunk fell into the river below. Slowly the Mississippi's only waterfall receded upstream, and created the gorge.
-Written of the Mississippi River Gorge by Stephen Long in his book Skiff Voyage to the Falls of St. Anthony in 1817
The rate of the waterfall erosion in the gorge was first calculated by geologist Newton H. Winchell in the late 1800s. Geologists today say that his estimates were quite accurate.
A Great Rapids Becomes "Pool #1"
Dakota Indians and European trappers who paused along the gorge in spring travels two centuries ago gazed at a river dancing with foam and spray around green islands, and listened to the roar of the river's most powerful rapids. Giant sturgeon, catfish, and paddlefish sought out the rapids. Eagles eyed the head of the rapids for a ready meal.
By the 20th century economic ambitions drove people to construct a new vision for the river. The river's first lock and dam rose to span the river gorge just below the former Meeker Island (north of present day Lake Street Bridge) in 1907. But it was short-lived. The larger "Lock & Dam #1", completed in 1917, flooded the gorge to accommodate barges and generate hydro-electricity. The numerous islands once seen in the gorge were flooded or dredged away. "Pool #1" had replaced the great rapids of the gorge.

Explore the Science Museum of Minnesota's Mississippi River Gallery, or the National Park Service's Mississippi River Visitor Center, also in the Science Museum in St. Paul. Visit Lock & Dam #1 at West River Parkway and Godfrey Parkway, and see St. Anthony Falls, and Locks & Dams, downtown Minneapolis. Go to Minnehaha Falls to observe the same geological process that formed the Mississippi Gorge.
