River gorge history highlights
Spanning from downtown Minneapolis to roughly fort Snelling, our nearby river gorge is the only true gorge alongside the Mississippi's whole 2,350-mile period.
45,000 to twelve,000 years in the past, during the last ice age, glaciers superior and retreated generally over this vicinity to slough away all the younger or top layers of rock formations.
The glaciers melted 12,000 years in the past, forming a massive quantity of water to create our current rivers.
Saint Anthony Falls become shaped 12,000 years in the past close to what's now downtown Saint Paul. The falls receded upstream for 12,000 years to their modern-day region near downtown Minneapolis.
Yep, you have the only true gorge on the river, but it is a dandy. The walls are quite sheer because of the composition of the underlayment. I spent some time in the region just east of there this summer where there are rolling hills and fairly steep valleys. Impressive country.
Yep You @right dear @bigtom13:):):)
