Sometimes, it requires multiple tries and different points of view.
For this challenge one image that is working is the following one:
We recognize the same landscape in the results.

After a quick search on Google Maps:
Go in Street View mode to better identify the location:
https://www.google.com/maps/@34.3944781,-119.5237992,3a,73.6y,232.47h,97.79t/data=!3m6!1e1!3m4!1s3uWURi3Jgu0vOY8Ar6eezw!2e0!7i16384!8i8192?entry=ttu
