can't even imagine how much that must frustrate the ranchers, outfitters and land owners who've been able to keep a lot of that information to themselves.
Definitely true, hell I've had spots get destroyed by onxmaps once people realized there was a tiny strip of access, that being said I think the idea that anyone is trying to intentionally obscure anything(not that you are suggesting it) is just a conspiracy theory.
Nameless, highlights a huge issue with contentions access issues. Further complicating this is that there isn't just one type of easement. Their are prescriptive easements that simple mean a road/trail is open because people have been using it without permission for a long time, there are easements with local governments, the BLM, USFS, etc. There are also land swaps, boundary corrections, and a bunch of errors. Also easements often don't effect the tax liability of an owner so it doesn't prompt a boundary change of the property in the assessor database which is literally the only place for 99% of the country which has any comprehensive data set for landownership, essentially even if an easement is filed with the county it's not mapped and put on their layer because they only record "tax parcels." Similarly no county in the country, to my knowledge, maps mineral ownership. I work in the Oil and Gas industry and part of my job early on was to help our land department determine title for the various pieces of property that we wanted to lease or had leased and needed to cure before we drilled. In many areas this is hugely difficult and mistakes happen all the time, I have spent countless hours trying to figure out the boundaries of various properties with documents going back to the 1700s in West Virginia and parts of Texas. Landowner's will sometimes convey surface ownership to conservation groups and retain mineral ownership by accident because of the type of instrument they used, 2 generations later an OG company has the rights to drill under a state forest and all hell breaks loose.
Here is a perfect example, my father-n-law, made a deal with the BLM a while back to create a public easement across his property. Basically he provided access, they gave him a couple of acres that were contiguous with his property. At the same time he also did a conservation easement on his pivot system. A third party conservation organisation managed the whole process so the grantor/grantee on the county website show an LLC not the BLM so you can't look up the easement easily. Also even though my F-I-L changed the signage on his property, and filed the easement and swap with the county the BLM didn't change their records. For 5 years or so Onxmaps show the boundary incorrectly because they were relying on the BLM dataset rather than the county, and it didn't get fixed until I plotted the easement via the metes and bounds legal description from the agreement, created a shapefile and provided that in person to the regional BLM office. The only reason I was able to get this done was I had the agreement in hand, the local game warden knew the road was open because they drove up there all the time, but the 25 year old tech in the BLM office had never been to that part of the state and all they had to go with was the layer in the system. No one had sent a copy of the easement and swap to the GIS department and said "hey this was just filed, update our records". If you had called the BLM in 08' they would have told you the rancher was posting public land as private and that you couldn't drive up the road, if you had called the warden they would have told you different.

I realize this is a long ramble, but basically land work is a PITA and access is hugely complicated on so many levels.
