If you are struggling to get the two achievment here is a simple solution to unlock them!
What u need 2 do!
I found a solid solution.
Use the seed: 47986332
and in addition in the mode, the attitudes as in the screenshot.
(This has worked for me without problems.)
Take the lifeboat and go directly to the first island that is marked.
I was on the mid island first.
There is also Wollie.
I picked him up AND LOOK, THE ACHIEVMENT appeared.
(EVERYTHING ELSE I picked up too,
as it is often said here in the forum, just to be sure)
After that, make a small raft (because faster than rowing)
and use the compass to go to the other islands.
(Choose a sensible order for you).
Collect as I said everything and have also taken precautionary everything with you to take no risk.
When I reached the third shelter and collected everything, the last achievement Archaeologist appeared!
I hope I could help you, do you need other help with an achievement, write me.
