Is cold brew coffee with coldish water and no refrigeration possible?
Sometimes when backcountry camping, I will have my cold brew sock and access to fairly cold water (just barely possible to go swimming) , but of course not a refrigerator.
It will stay fairly cold through the night probably dropping to 40° F.
Would good tasting cold brew coffee be possible under those circumstances?

The short answer is yes, it's perfectly possible to make cold brew coffee in these circumstances. The main reason it is typically made in a refrigerator is to keep it from being lukewarm and therefore less palatable. If you don't mind the coffee being 40(+?) degrees instead of 34 it should be fine.
The coffee will also become stale or develop bacteria more quickly than in a refrigerator, but if you drink it within a day or two it should be fine (ordinarily it will keep up to a week or so when fully chilled).
