What analogy does scout use to describe aunt alexandra?

Scout compares Alexandra to Mount Everest:  "She was cold and there."  Scout finds Alexandra to be "cold" because she rarely expresses any feeling or emotion except perhaps disapproval, which is almost always directed at Scout's clothing, or behavior, or some combination of the two. Scout finds Alexandra to be "there" because she is Atticus's sister, thus a part of the family, and an inevitable part of Scout's life.

Scout also had a unique assessment of Alexandra's general appearance, commenting that the clothes Alexandra chose "managed to suggest that Aunt Alexandra's was once an hour-glass figure.  From any angle, it was formidable."

We’ve always heard that the black widow is one of the deadliest spiders in the world, but while this is more or less true, it’s just not saying much. Completely unaggressive towards larger creatures, widow bites are quite rare, and lethal bites are even rarer – those at risk are normally only infants, the elderly or those suffering some pre-existing medical conditions. They’re still creepy though, right? With that whole “devouring the male” thing. Yeah, about that…of the 31 species of Latrodectus or “widow” spider, only two species have been observed eating their mates at all, neither of which are the famous red-hourglass black widow, and the cannibals in question were likely just frightened by their gigantic human voyeurs. Though the male is weak and snack-sized, the larger female normally allows him to escape or even hang around in her web a while, where her presence makes him a tad safer from an assortment of spider-eating things.
