Couple of news releases on there about airborne geophys scans taking place. Normally electromagnetic scans either for geological structures or groundwater.
I don't think this is a government survey-it was done almost exclusively over mine owned property. An engineer from that mine went rockhounding with me yesterday, he claims it's just making a new topographic map of the area, but since the new pit hasn't begun yet I doubt the topography has changed enough to require new mapping. I personally figure it's some sort of magnetometer to define the limits of the ore body, but the mine probably won't tell me the truth-they haven't yet except when they admitted if they destroy our aquifer our only recourse is to sue them.

Gravity survey is also a good possibility.

All you bikers can prolly tell me what kind of iron this is...

Can't comment on the make of the bike, but I though GPS in 1970 on a bike would have been the old lady in the sidecar with the map whipping in the wind shouting instructions to her husband.
