The Wheeler map made in the 1880s shows a volcano between what is Victorville and Barstow.
The questions is; Is the “Volcano” either Stoddard Mountain or Bell Mountain?
Volcano location on 1880s map.
This USGS map shows the location of both Stoddard Mountain (yellow dot) and Bell Mountain (blue dot).
Both maps are superimposed and reconciled to critical match points.
The USGS map layer is replaced with the 1880s map layer and the layer with the location dots is turned on.
So it looks as if the “Volcano” is nowadays known as Stoddard Mountain.
Maybe next time; Is Stoddard Mountain a real volcano?
