Remember the Lower Loon Lake challenge from FSX? I created a flt pln with a C172 Original @6500'MSL pointed 230'M approx heading to Loon Lake for MSFS 2020. Extract the three files contained in attached archive and put them where you keep your saved flights. To find that, open saved flight in MSFS 2020 main menu and note the path to your saved flights. Once extracted, go to the main menu and open the plan called  "lake". Follow the river down heading 235M until you see airport C53 appear on your Garmin . The strip is narrow and short at 4100MSL. Have Fun! I didn't see that old bear that used to be there, but you never know...

 

I dont use POI references, so you might want to turn those on to find the lake. Turn off autopilot when the plane starts.
