It is called prepositional because it consists of a preposition (in this case, through) and another word or phrase - for example, a noun (in this case, valley). Prepositional phrases usually function as modifiers, which modify a noun or a pronoun (like an adjective does) or a verb (like an adverb does). In this case, the prepositional phrase functions like an adverb. It modifies the verb "to drive", answering the mental question: drive where/when/how.

The prepositional phrase would be "with the full moon". It would stand by the subject (scenery) and would answer the mental question "what kind of scenery".
