Description

I came across what I believe *might* be the map Luigi Venditelli referenced on the Rogan podcast (https://www.youtube.com/watch?v=Lb\_1d68vx-g&t=9613s (https://www.youtube.com/watch?v=Lb_1d68vx-g&t=9613s)). I’m not 100% certain this is the exact map he was referring to, but the more I study it, the more it lines up.

I did send him a message on IG asking for confirmation. Though I didn't get a formal response, he did "love" my message and the link to the map... take that for what it's worth.

This is the 1942 Emigrant Valley quadrangle, compiled using 1941 aerial surveys. It appears to show Groom Lake (top), a smaller playa southwest (very likely Papoose Lake), multiple unimproved roads/tracks, several mining features

A couple things stood out to me:

1. There’s a distinct unimproved road that branches off and runs INTO the mountain where S4 is reportedly located. This is just like Luigi described.
2. There is also a mine there, which would explain both the access road and the possibility of existing underground excavation. Also, just as Luigi described.
3. When comparing to later maps, that road and the mine label are gone.

I'm not 100% certain because the shape of the playa/Papoose Lake doesn’t match modern satellite imagery perfectly, but it’s *pretty* close when you consider its position relative to Groom Lake and the surrounding terrain.
