What plate are the Neenach volcanics located on?
North American Plate
The remnants of Neenach volcano on the east side of the San Andreas fault are located near Neenach, California (north of Los Angeles) on the North American Plate. Figure 1.
What happened to the volcanic rocks of the pinnacles volcanics after they erupted?
After the volcano’s eruption, lift from the San Andreas Fault combined with millions of years of erosion created the great valleys and pinnacles of Pinnacles National Park. Straddling the San Andreas was actually split in two! The other half is 195 miles away near Lancaster.

Why are there no volcanoes in New York?
The geologic forces that generated volcanoes in the eastern United States millions of years ago no longer exist. Through plate tectonics, the eastern U.S. has been isolated from the global tectonic features (tectonic plate boundaries and hot spots in the mantle), that cause volcanic activity.
Can lava come out of the ground in Texas?
Volcanism: Volcanic eruptions were plentiful in the Texas Hill Country during the Cretaceous period, at around the same time as Pilot Knob. A number of lava bodies can still be seen in the Uvalde area.
