For camping in National Forest go the web site for the National Forest area you are in and find the ranger district. From the ranger district in combination with the main National Forest web site you can find camp grounds, rules that are in effect and most important fire restrictions or closures due to fires or flooding.
To check to see if a GPAA claim is valid just check on the Online Mining Guide, if the claim is in there it is good, for further information go to the LR2000 on the BLM web site. Look up the claim by name or geological location. A claim is valid until the BLM voids it. The BLM is the only agency that can void a claim. If the county, Forest Service, Fish and Wild Life wants a claim to be voided they petition or report to BLM to ask them to void it. The county is the location of recording which is required so those records are there also but the BLM is the Claim Filing Agency and is where the Adjudicators work from for Federal Mining Claim adjudication.
The information above is not the only location to find this information but it is all free and downloadable to a computer. I am not sure how smart phone friendly each is but for the most part they say that a smart phone will work. Some do have downloads for the smart phones.
