Here is a link to the Santa Fe national forest website, that's where Jemez springs is.
Santa Fe - Rocks & Minerals
Its your job to know the status of the land before you head out. It is also your right to prospect, there is no way in Juarez I would ask a ranger permission
to do something that I have the right to do.
Again, It IS YOUR JOB to KNOW the STATUS of the land you are going to prospect. It kind of sucks, it requires a lot of research. I've never dealt with
forest service land, but it shouldn't be too hard to find out if an area is open to mineral location. It pretty much tells you on that page I linked to, where you
can't prospect.
Then of course you have to respect peoples claims.. That opens up a whole other can of worms, and more research. Land matters is a good starting point.
Maps, Mining claims, New Mexico mining claims... That can give you a good idea of the land status and how many claims are in each section. If there are
claims, its a good indication that there is gold there. Then how do you know where the claims are in each section? The BLM can't tell you, there is no map
out there that tells you. You need to head on down to the county clerks office and start pulling paper work and piecing it together.
Unfortunately it isn't as easy as asking a ranger, or looking at a map, it sure would be nice if it was, but it isn't, and we have to live with that.
