How did the settlers in the 1600s New World describe the new land they found?
That depends on who you asked and where they had settled. The initial settlers, in Virginia and Massachusetts, had different views upon their arrival.
In Virginia, they chose Jamestown as a settling point merely because it was conveniently their spot of arrival. It was actually a very poor choice, as that part of Virginia (at the time) was a mosquito-infested swamp. The settlers of the day described it as such, as land which was difficult to live on, even as the climate was favorable, the rivers easy to navigate and the soil ideal for farming. They still found the environment there a little daunting for a self-supporting venture.
In Massachusetts, they looked at both the land and at what it represented to them. These were religious pilgrims, and even though the land was rocky, cold and wet, to them it meant freedom of religion, and freedom from persecution by the King. So their diaries, at least initially, speak of a more promising land for settlement, even if compared to Jamestown, it wasn't.
