Through the Mountains of Madness

About midway through the story, I'm sorta scared. The way that Lovecraft describes these people wandering through ancient ruins of a hgih society that time left behind is so detailed, and reveals the beauty of the fictional world that Lovecraft creates with stunning accuracy. The plot describes an expedition party going to a yet unexplored mountain range, when they discover frozen corpese of some foreign race that appears to have bodily processes of both plants and animals. They decide that they must explore further, and they send a party ahead of them. This party doesn't return, so those left in the expedition decide to go looking for them. They go ahead in a small plane, and find themselves flying over some ancient, abandoned alien city, so like normal, sane people, they explore it. They're looking through this ruin, but the way lovecraft describes the situation makes me feel like something's waiting for them in the darker corners of this abandoned place. The overall apprehension of the writing really creeps off the page and into your mind.
