Anybody know what the groups of straight lines perpendicular to the road are?

From Google Maps here - if you scroll around there are lots of them in the area.
Doesn't really matter, I'm just curious.

I'm guessing they are part of a "thumper truck seismic survey", which is how they look for oil among other things.
A thumper truck is a vehicle-mounted ground impact system which can be used to provide a seismic source. A heavy weight is raised by a hoist on a truck and dropped, generally about three meters, to impact (or "thump") the ground. To augment the signal, the weight is usually dropped numerous times in a known pattern to enhance the seismic signal by spatial filtering.
Thumping replaced firing explosives in a shot hole in the 1950's. Thumping is considered less damaging to the environment than firing explosives. But the down side is the thumped seismic line creates long-lasting disturbance of the soil.

Ran into one one time out by dead horse point. Pretty impressive when they drop it.

Makes sense, thanks!
So that's the "Universal Vibrator" huh... wonder who came up with that name. :)
Interesting. I was wondering what causes lines like these near some of the mountain peaks. Take one of my videos here, at the 35 second mark. Are these similar?

Nope---that is mountain terracing for erosion control, completed by the CCC

Definitely not Nazca Lines.
