Questions this course answers

What is the Colorado Piedmont in this course's map of Denver?

The Colorado Piedmont is the Great Plains landform at the eastern foot of the Front Range, where Denver sits.

Why did the South Platte–Cherry Creek confluence matter to early Denver?

The confluence supplied a practical location for settlement and movement; the gold rush then brought miners and settlers.

What changed when Denver channelized the South Platte?

Channelization and hardened banks constrained the flood-prone corridor and made room for roads, rail, parks and industry.
