This is a vacation with my wife and two kids ages 10 and 8, I'm only
staying two days at Yellowstone. I'm coming from Michigan in a turbo
Twin Cessna (C320), but my wife would like to avoid using oxygen, but
I do have onboard oxygen in the plane. My last fuel stop is going to
be Rapid City, SD (RAP) from there I'm planning routing direct to
Crazy Woman VOR CZI V324 RLY(Worland VOR) V319 COD(Cody), then direct
to WYS(West Yellow Stone). I should be able to stay at 12,000 until
Cody. I called Salt Lake Center, they looked at their charts and said
there isn't a MVA, but the Minimum IFR Altitude (MIA) between Cody and
West Yellowstone is 14,300, but he thought there was an area that I
could get vectored at 14,000. So I'm not expecting to need to go
higher than 15,000, I'll be using a cannula, but my family shouldn't
need to since I shouldn't be up there for more than 30 min.

Any reason you can't go VFR after Cody? The weather this time of year is
generally pretty good unless there are afternoon T-storms (which you wouldn't
want to tangle with VFR or IFR). I've flown COD to WYS numerous times at 10,
500 ft. (following the highway).

I spent a couple of weeks at WYS last month. It's a good year to go. Not
much in the way of fires in the region.

Tell the folks at Yellowstone Aviation that John in Phoenix says Hi.
