Note that the Mystery Lake map is outdated. The Destroyed Tower is located where the Forestry Tower is shown on the map. The Forestry Tower is now to the southeast, on the peak of the hill where the Frozen Creek waterfall is.
Here's the important part: you don't need to go anything that doesn't have a loading screen. That means no cars, no fishing huts, no abandoned buildings. Also, no prepper caches. When I went to Mystery Lake, I couldn't find the cache that was on my map, so I didn't go in. The achievement still popped.
While doing this, don't forget to map all the locations for Faithful Cartographer.
Hope this helps!
Best to get this over with on Pilgrim as you just need to go to every indoor location, and hostile wildlife as well as harsher weather enjoys getting in the way of it
You don't need to find the Prepper caches, but you do need to enter the Forestry lookout.

Also note that the Mystery Lake map is outdated. The Destroyed Tower is located where the Forestry Tower is shown on the map. The Forestry Tower is now to the South East, on the peak of the hill where the Frozen Creek waterfall is. If you're at the destroyed tower you can see the new tower just next to you. If there is a rope in the stash you can use it on the rock on destroyed tower side towards the new tower to have a short cut.
