Where to find a map of tunnels under Salt Lake City?

So I was browsing through a book store across the street from the Mormon temple and discovered access to the tunnel system underneath down town Salt Lake City. I would love to do some exploring down there. Anyone know where I might be able to find maps for Salt Lakes underground infrastructure?Where to find a map of tunnels under Salt Lake City?
I don't think there are any public access maps. the tunnels are not public access, but they simply connect the church buildings....nothing extravagant.



more interesting to me is the supposed tunnel system under the city of ogden utah (which had nothing to do with the LDS of course but was much more extensive than a tunnel between two buildings)....especially the old 25th street area. there were supposedly lounges and gambling and private offices/quarters under the ground - a real 'al capone type speak-easy' sort of a thing....a kind of connected storage area under the shops and stores used in the 20-30-40's during times when prohibition was in place and laws against gambling. I've also heard possibly prostitution and opium dens but who knows. most of it has been closed off and abandoned, but some storage is still used.

there was a fair contingency of chinese in the ogden area and I wonder if they weren't involved there similar to the tunnels in moosejaw canada (where one tunnel collapsed under a truck in the 70's).

I don't think the tunnel system under 25th street was ever as extensive as some say (running all the way to union station and such) but I suppose it's possible.

this was one of the roughest and most dangerous parts of utah history. @one point - ogden city was looking to see about opening up and restoring some of this.....absolutely fascinating.
Yea and did you know they have a Mormon vault in UT Mountains where they keep all the records as well, it is atomic proof. The tunnel system is only for Mormon Apsotles, there is also levels in the temple, the an Apsotle can go to the top level when he needs to speak to God, sounds like the Tower of babel to me.Where to find a map of tunnels under Salt Lake City?
Older libraries. Civic buildings. Planning Dept. Look in the older parts of the SLC PD records. There used to be a ton in the far back. Huge dark green books. Can't miss 'em. IF they are still there.



Sperlunking in SLC. Sounds like a rap song!
It is my understanding that there are some underground passages between the Temple and the church office building, but they are private and not open to the public. It wouldn't surprise me if the Conference Center is also connected.
