Describe the valley of ashes what does it look like and what does it represent

It represnt absloute poverty and hopelessness.This quote explains how does it look like "This is a valley of ashes – a fantastic farm where ashes grow like wheat into ridges and hills and grotesque gardens; where ashes take the forms of houses and chimneys and rising smoke and, finally, with a transcendent effort, of ash-grey men, who move dimly and already crumbling through the powdery air. Occasionally a line of grey cars crawls along an invisible track, gives out a ghastly creak, and comes to rest, and immediately the ash-grey men swarm up with leaden spades and stir up an impenetrable cloud, which screens their obscure operations from your sight. … The valley of ashes is bounded on one side by a small foul river, and, when the drawbridge is up to let barges through, the passengers on waiting trains can stare at the dismal scene for as long as half an hour.” (Pg. 26). It's a place where lower class want and wish to leave it but cannot, an example is Myrtle who dies trying to escape the Valley of Ashes.
