It depends on what the italicized phrase is.
If <em>on the frozen lake </em>is italicized, then this is a prepositional phrase.
Because it begins with a preposition <em>on. </em>
I believe that the answer could be absolutely anything, if so then “extreme” and words similar to it could fit there.
“A flash of extreme joy appeared upon the woman’s face.”
