I'm right now at the indicated location (43.8122, -173.9722), and here it is the crashed Anaconda, in a very steep slope, with difficult access. There is no persistent mark or POI, but I very clearly detected the crashed ship with the SRV radar, when I was close to the target location.
There are pleny of canisters full of Bertrandine, and also some cargo racks, which can be destroyed in order to access the rare materials inside. I landed my Python at 43.8643, -173.9874.
Thanks a lot for the location!
