This trip is meant to be played without GPS. I would recommend using LittleNavMap with google maps satellite layer. - https://www.avsim.com/forums/topic/548994-new-maps-for-lnm/
Just set “show aircraft position” and “show aircraft trail” to off.

The terrain is quite diverse and has so many features and color so  it's really easy to get disoriented. Be prepared for some  backtracking and have some places to return to if you get lost.
Most waypoints are set to road crossings
There are some landings on top of mesas but nothing to hard.

If you like this one I made one with simmilar terrain in Turkey. If you crave more STOL landings and a real challenge check out my Idaho flightplans
