Robert Frost’s inspiration for his poem “A Cliff Dwelling,” appears to be his wonder and curiosity of an ancient society that once was but is no more. Frost’s words indicate that these ancient people are all but forgotten by those who live on the land now. He wants the readers of his poem to know that at one time these people were very much alive and strong. Frost seems to feel sad, frustrated, annoyed, or a combination of the three emotions that whatever catastrophic event or chain of events occurred to seal the fate of these people rendered them as unimportant by society today.
