One of the field crew found this survey spike the other day. I can't say that I've ever seen one exactly like that

Strange how regional survey evidence is. That is probably one of the most common things I use over here.
Gin Pins and axles on the other hand are incredibly rare, and I have never actually seen fat wood/lighter wood hubs.

We would call that a 'Road Nail' - normally used for engineering work rather than cadastral.

Ours have a cross incised into the top

We find spikes all the time in WA, but never in ID.

Surely it's not used for a property corner. Topo traverse point?

Spike around here refers to either a large nail of some variety or a railroad spike.  On occasion it will be prefaced by: boat, landscape, timber, bridge, etc.  Sometimes it will be a 60d or 80d nail.  Never see the term applied to a short nail or screw of any kind.

it is a Chris-Nik Mag Spike. They are larger diameter than mag nails. Nails are about 1/4” diameter, spikes are about 3/8.

I primarily use them as survey control or as temporary placeholders for setting monument cases. (Survey positions first then come back with cases, jackhammer and concrete). On rare occasions, they stand as section corners, due to the corner falling on a bridge…. Irrigation canals here commonly follow section lines. Of course in those cases they include a washer with required details.

They are most commonly found at road intersections and are most commonly found to be out of place and/or no record of where it came from.

We used to see "PK nails" of all sizes at road intersections, etc. More common now are Mag nails or mag hubs of similar size as the PK. I don't recall seeing one before with that stamping or that size.

Road intersections? Great flat tire device in snow country.

the domed top is easily disturbed. here in the pee dee region of south carolina we have ice and snow only one or twice a year. those tops are easily taken off by the Motor Graders that are the main scrapers here. i try and tell my guys to drive things in the roadway to flush or below. i have told them to do minimal marking also. we mostly us Mag -Nails as an auxillary control line. not se them near property lines that would show something has been changed. no matter what you try to do, people look. we try and to speak to every adjacent owner but people always think we are doing something underhanded. they yank up nails, rebar that we replace and even old found corners. bite your lip and keep doing it the right way is what we try and do. Yes we make some mistakes as everyone but we try to do it right.  ya'll be safe. training, reminding your guys about stuff is really important i believe.
