Map of shelter/huts in the White Mountains – New Hampshire – April 26, 2023 at 05:10PM

Looking for some reference to the open faced, three sided structures in the white mountains for overnights – not to be confused with the AMC bunk houses with meals for a large fee (great option but not what I’m looking for).

Does any such reference exist? My angle is to do back to back day trips while sleeping in a place like this rather than a motel. Car camping is an option but heard it’s discouraged and most probably will get asked to leave during the night.

Any suggestions??
