One look at the art work and you can tell immediately that Blood Mountain is a concept album about the life-and-death struggle faced when one is lost in the wilderness, climbing a mountain at night and under the influence of some kind of transpersonal shamanistic sacred cacti. Right? Also, the album (their second concept attempt; 2004's acclaimed Leviathan, was about "Moby Dick") represents the elemental nature of the earth. Yeah, these guys are weirdos. You might want to avoid "Circle of Cysquatch" and "Bladecatcher" until the cactus has left your system. Or not.
