Heavy fog is SLC the evening of January 23rd. Some interesting diversions:

DL 4588 IAH to SLC (diverted to CDC)
DL 1238 TPA to SLC (diverted to GJT). This flight looks like it got to Provo
DL 4880 STL to SLC (diverted to GJT)
DL 4889 DFW to SLC (diverted to GJT)
DL 4869 YVR to SLC (diverted to DEN)
DL 4483 OKC to SLC (diverted to COS)
DL 4551 TUL to SLC (diverted to COS)
DL 4770 MCI to SLC (diverted to COS)
DL 4485 OMA to SLC (diverted to COS)
DL 4674 BUR to SLC (diverted to CDC ... seems cancelled at this point)
DL 4469 MSO to SLC (diverted to IDA ... seems cancelled)
DL 4908 PVR to SLC (diverted to LAS)

There are probably others. I'm live in SLC, but an not sure if these are typical airports for diversions. Surprised COS and GJT wins over DEN. Not sure what they do with passengers in CDC if the flight gets cancelled.

Typical diversion airports for OO's SLC inbounds are PIH, TWF, IDA, GJT, CDC. I'm surprised they sent them as far as DEN and COS to tell you the truth. I'm glad I wasn't in OCC.

Well it looks like OO is now in diversion recovery mode and is in the process of getting aircraft at least into SLC for the evening.

CDC got to see a CRJ-200, 700 and 900 diversions, they normally only see two EMB-120's a day. They also had a training flight earlier in the day on OO's brand new CRJ-900 N825SK. They had a busy day.

When an inversion layer develops in the Salt Lake valley, it can take days or even weeks for it to clear. In Jan '86 the whole month we had fog. You had to go up to the mountains to warm up and get some sun! As for the diversions, Im guessing that DEN has higher landing fees than GJT or even COS, so that has something to do with where they drop in, along with other logistical issues. Provo does not have a commercial terminal, and it would take some coordination with an FBO or other ground handler to allow pax to deplane there. I doubt, they would though.

It's interesting this has been mentioned on here as last evening I was discussing the heavy fog at SLC with my friend who is a dispatcher for a major U.S. airline. He gave me the weather at that time as 232353Z 34006KT 0SM FG BKN001 OVC006 04/03 and I commented that that was pretty darn low visibility indeed.

COS and DEN were used to spread the diversions around. With a major bank inbound to SLC at that time and RVRs holding between 100 and 500 for several hours everything had to divert. Rather than overload the cities closest to SLC the decision was made to land aircraft further out based on where they were coming in from. It was pure CHAOS for several hours!

RVRs at that time were down to as low as 100 feet, and for the most part stayed at or below 500 feet, which is what most all carriers need to even take off.

As AH4 said, COS, DEN, and CDC were used to spread out the diversion load. Too many airplanes at one airport = bad. Also, it's not that DEN has higher landing fees, but rather, has limited ability to handle diversions with Delta. Cost is NEVER put in front of safety.

Also, the GJT and COS diversions were for those that were near them at the time. Most of the SE arrivals were holding over VEL (Vernal, UT) and MTU (Miton, near Vernal,) so GJT and COS were logical (and legal) at the time.

PVU and OGD are never a first-choice alternate, but when fog hits as suddenly, and as thick as it did, there's not much that one CAN do.

I remember that. I can recall that when one of the DL flights landed, we had to go find them with a tow tractor and tow them into the gate because they couldn't find their way once they hit the taxiway. They could be as close as the end of A or B concourse (our gate was D-1) and that was as far as they could get.
