Yeah. Salt Lake missed out on a great deal of pre-modern towers because, as the city grew to support 'em, there just wasn't an economic market to build that vertically like in other cities. The Walker Center really is the gem of all those towers - having topped out as SLC's tallest for a few years until the capitol was completed (and the tallest in the CBD until the Kennecott Building - or Gateway Tower East/Zions Bank Tower - finished in 1962). But without a Great Depression, SLC could have seen a new tallest in the form of a pre-modern tower (something significant, to boot, and not dwarfed like the Walker in today's skyline).
Imagine this as SLC's tallest from 1930 to 1973!
