You might be able to find it using the TXT flight log from your mobile device. You can upload it and view it online here. If you need help tracking it down, please post a link to your log here after you upload it.
Inside the DJI Go app, there is a setting that will show on the Google Map where it last had signal.....when I crashed mine it led me right to it. It's called 'find my aircraft' or something, can't seem to find it now, but it's in there. Litchi has it too. Should take you pretty close as long as it was in range when it went down.
DJI GO does not have a "find my aircraft" feature. You could see the last recorded location when viewing the flights in DJI GO though. The data is much more limited than viewing the flight log itself though.
