How is the landscape around the house investigated and described by the narrator and his friend?

Initially, the narrator describes the area around the hamlet of Kraighten, where they set up camp, as 'a waste of bleak and totally inhospitable country' that is 'bare and unpeopled', with the earth scarcely covering the underlying rock [1].

During their exploration, they discover that the river they were following comes to an 'abrupt end vanishing into the earth' [1]. This leads them to a 'wilderness of bushes and trees' that the narrator realizes is a 'great and ancient garden' [1]. Further on, they encounter a 'tremendous chasm' with a 'monster cataract of frothing water' [1]. Perched over this abyss, they find a 'fragment of a great ruin' [1]. They also discover a 'great lake of silent water' to the north of the chasm [1].
