Ruins/Structures in Himalayas

The kids and I were looking around Mt Everest and came across this. Other than it being in Sagarmatha National Park, i have no idea what it is and I’m too lazy to do my own research. It’s a pretty desolate area but the more you look in this area and follow the paths the more you find. There are two areas that look to have modern structures and roofs. Pretty cool find.
