Answer: The Turquoise Lake as seen nowadays in Colorado is a result of the 1850´s modern warming climate transition, lingering away from the Little Ice Age times occurred 500 years ago. This given period was characterized by snow blowing winds that accumulated ice through thermal compaction, generating the glaciers as we see them.
Explanation: Terminal and recessional moraines are the terminus of a glacial feature. Moraines are the sedimentar charges carried by melted glacials. Consequence of those is the repositioning of the snow downwards the valleys. The ice, initially attached to the glaciers and mountain tops, undergoes melting by seasonal and/or climate transition warming, resulting on circumstancial water deposits that place on the basin/lower areas of the mountain chains, forming lakes.
Cities are urbanized areas, farms are rural areas, so basically urbanized areas are areas with a concentrated amount of people and buildings and factories and technology and all that
