For those of you who were thinking about filing a claim and may not know the rules and regulations for filing a claim, the office of the BLM at 2850 Youngfield, Lakewood, Colorado 80215-7093 has packets available to give you all the information on mining claim rules and regulations. If you are not sure where the BLM office is, it is off of I-70 at Exit 264.
After being armed with this information from the BLM, you may need some maps about the area you are interested in filing a claim or just going to try your luck at prospecting. A good place to go would be the Federal Center on Kipling just south of Highway 6. As you come to the gate the officer will ask for your ID. Tell them where you are going, which is the USGS Map Store. They will direct you from there.
Once at the Map Store, you can get a map of the area you are interested in. The maps that you want are the 7.5 maps. They are very helpful at the store so don't be afraid to ask questions.
I hope that this information will help you out in finding maps and information that you need to locate and file a claim or just go prospecting in an out-of-the-way place.
Good Luck in your Nugget Hunting.
