Prospector's Research Tools

Recommended Posts

Alright now you have a map with a bunch of colored squares on it. I'm sure you've figured out you can zoom in to an area and get some information about what's on the map by clicking the [ i ] symbol but how to heck can you get some real useful information. You know like finding out just which claims were new in the update.


You can make the job of seeing what claims were updated when and where with a little search magic.


You know that pair of Binoculars on the right side of the map? You are probably thinking we just put that there to confuse you - right? 200.gif

It's actually a really cool feature once you learn to use it. I'll give some examples:


First open the Arizona Claims Map.


1. Go ahead and click on the Binocular symbol while you have the Placer Claims layer turned on. An imposing form titled "Query Editor" appears on the upper left corner of your map.


2. Select the name of the map layer you want to search in the "Layer Name" dropdown box at the top of the "Query Editor" window. Let's start with "BLM LR2000 Placer Claims" for this example.


3. Skip all the other parts of the form for now and go right to the "Generated Query" box at the bottom and type (or copy & paste) this exact line:

[Claim Location Date] > '2014-10-1'


4. Click the "Apply" button.


You should now have a list of all the Placer Claims located since October 1st 2014. happy0199[1].gif


Hold on this gets even better! You want to know if any of those claims were made in your area of interest right?


Scroll to the top of that result list and find the column titled "Township and Range". Click on that title. Now the result list is sorted by the Township and Range. Just scroll down to see if there are any claims listed in your Township and Range. They will all be clumped together in a group. happy0199[1].gif


So you want to see on the map where one of those claims is? Just click the magnifying glass symbol to the left of the claim name and the map will zoom to the section the claim is in! happy0199[1].gif


I promised you search magic - wasn't that easy? You can change the date in this line to whatever you want:

[Claim Location Date] > '2014-10-1'


You could even search for claims between two dates like this:

[Claim Location Date] > '1936-1-1' AND [Claim Location Date] < '1952-1-1'

That will search for all claims located between 1936 and 1952. Just click on the "Claim Location Date" column head to sort those in order of date.


You can search for specific claims by name or any other quality you want just by playing around with different ways to fill in the blanks in the "Query Editor" form. This is searching on steroids!


Go play with it. You can't break the maps and you just might find the trick that gives you just what you were looking for.

This is a really neat feature Barry. I've been (formerly) in the surveying and mapping business for a long time. We specialized in aerial mapping / photography and cadastral (PLSS) resurvey and retracement. What you are doing here is truly a wonderful tool for the layman and professional alike and not just us prospector / miners.


Thank you,

Hey Mike thanks for the feedback! It means a lot coming from you.


Were you in on those Southern Oregon resurveys? If so you did everyone a real service. Some of those original South Oregon cadastral surveys were a real nightmare.

By request we've added a few new features to the Idaho Geology Map. We've added a Faults Layer and a new Idaho Rock Samples layer with 26,000 Rock samples taken from all over the State.


The Rock Samples layer has a link to the chemical analysis of each rock sample. The analysis is presented in an easy to read table broken down by percentage or ppm (parts per million) of each element.


Even if you don't have an interest in Idaho geology I hope you will take a look at this new feature and let us know if you would like to see one of these Rock Sample layers on your State's geology map.


As you can imagine building a map from all these samples takes some considerable time. I think it's a very useful feature not only for prospectors but for rock and gem hunters or anyone interested in the nitty gritty of an areas geology. If we get good feedback on this new feature we could begin to include it in your state's geology map.


Let us know what you would like to see. Contact Land Matters.

Thanks Mike, you are welcome. More Magic coming your way! :D


By request the Idaho Mining Claims Map is now available.


Idaho currently has:

18,983 Lode Claims

2,191 Placer Claims

436 Millsite Claims

16 Tunnel Site Claims

21,626 Claims Total


There have been so many requests lately for Idaho we've made this an Idaho weekend. Be sure to check out the new Idaho Geology while you are looking at those claims maps.

It's been a while since I posted a Land Matters update. We've been busy finishing up some private work but we've still made a lot of updates to the Land Matters Maps and Library.


Of most interest to prospectors is that we have now completed* the 12 Western mining states BLM LR2000 claims maps. All of those maps were just updated this weekend and as usual the BLM is still updating records from months, and in several cases years, ago. Lots of surprises there. Check it out!


We've split the Mining Claims Maps into two sections and created a new Mines Maps section that has several new maps to help your research.


The Land Matters Geology Maps section continues to grow. There are now 25 States mapped with new additions coming regularly. Each State Geology map will continue to have new features added as we find the time and resources. Some maps have more features than others. We build these maps mostly by request so if we are missing something useful let us know and we will get it mapped for you asap. You can Contact Land Matters directly, we'd like to hear from you. smile.png


We've got a new mapping set that should be useful for all lands users. The Land Matters Topo Search Map gives you quick direct access to download more than a Quarter Million Topo Maps. This includes the entire Historic Topo maps collection from the USGS. You can search by area and download old, full resolution, topo maps going back to 1882. Look up the old mines, buildings and roads. Many have hand written notations on the map from the time they were published. These are a great resource for most any research involving the land or history. Something for everyone there!


The USGS just released the new US Topo series for Arizona. These have several upgrades from their previous digital topos. Most importantly they now have the PLSS (Township, Range, Section) layer included. You will find those on the Land Matters Topo Search Map along with all the other topo maps being added every month.


There's lots more to come at Land Matters check in often.






* There are three claims in the State of Nebraska! We have not mapped those. blink.png

This is the first chance I've had to take a look at the new website. Very very impressive, what a great tool.


I am headed out on a detecting trip but, looking forward to really exploring the site when I get back.


Just made a donation. I hope a lot of forum members will jump in and help too.


Thank for all the hard work.

You are welcome Dick. Thanks for the donation! It will make it possible to pay the server bills and keep adding more requested resources. Like this...


The much requested Alaska Mining Claims Map is now available!


This map was tough. Alaska is one BIG state! The State of Alaska has a lot more State Land than Public Land. This is unusual in the western mining states. Alaska allows mining claims through their own state mining board. That's also unusual. This makes for a lot more State mining claims than Federal mining claims so the Alaska map has three types of claims displayed.


This new Land Matters map has both the State and Federal mining claims displayed. It's also our only map with the Master Title Plats displayed right on the map. This is shaping up to be one killer map! wink.png


There will be more features added to this new map in the next few weeks so keep a look out for more updates soon!



Thanks again

The previous older Geologic Folios have been very popular so we came up with another group of Geology maps for download.


We've added direct access to all 1,784 of the USGS Geologic Quads in the Land Matters Geology Library.


You can search for those Geologic Quads by quadrangle name or get the whole list to browse through by typing "gQuad" in the search box or by searching for "Geologic Quadrangle" with the state name.


These are higher resolution and more recent structural geology maps than the previous folios. Look around and I'm sure you will find something useful. wink.png


We've got lots more geology resources coming to the Library soon as well as a few surprise maps.

We've upgraded several of the Land Matters Base Layer maps big time.


You will find these Base Layers on every Land Matters interactive map. They form the bottom of the maps layer stack and provide a visual reference for the other map layers.


We've made the Aerial Photos ("Satellite images"), Topo and Street maps load about 4 times faster and increased their color quality. For those of you on faster connections you will see a big difference in load times and quality.


We've increased the ground resolution of most of the Aerial Photos by more than 3 times. Ground resolution is a whopping 1 foot in most of the United States now!




We've also upgraded the Real Time Weather Map. This map now has higher resolution real time radar that will let you see the progress of storms anywhere in the United States as they happen. The real time infrared satellite updates show cloud masses and their movements right along with the radar day or night.


Just click on the "Refresh Map" button to watch the radar and cloud imaging change as the weather changes. You can zoom in and out and move the map just like any other Land Matters map but the map shows current weather conditions.


These weather maps are one of my favorites when I'm planning an outing. Get the real thing at home when you need it.


More coming soon!

Land Matters Claims Advantage Members have been receiving their twice monthly Closed Claims Reports for about a month now. These reports can be very helpful for someone doing claims research and might be used for several things. Maybe even finding recently opened land for prospecting or mining claims? ;)


In addition to the twice monthly update reports Claims Advantage Members are emailed a series of Special Reports as they are created. There have been two Special Reports since the Land Matters Membership program was started last month. These reports are about 15 pages long and have State by State interactive tables to help claims researchers.


I can't share the reports themselves but with each report Land Matters includes heat maps to give a visual aid in identifying the most active areas. Special Report #1 presented Placer Mining Claims that were closed within the last three years AND were more than 30 years old when they were closed. This was an interesting report because claims that are more than 30 years old are usually considered valuable and worth keeping. Not your average exploratory claim that lasts for a year or two. Useful information for the clever prospector.


Here's the heat map from Special Report #1. The map shows the areas with the most closed Placer claims as a deep red and then fewer claims density are shaded down from lighter red to pale yellow. The smaller black lines are county borders to give you a little better idea where the activity is taking place.




Although this map is nowhere near as detailed as the full report it does give a good view of where the claims changed and even potentially tracks areas of higher mineralization and claims interest. The report itself shows for each claim 14 data fields and a direct link to the BLM records for the claim.


The Special Report #2 is similar to the first but deals with 30 year lode claims. Neither of these Special Reports or the twice monthly Closed Claims Reports could be created from LR2000 information.


We are working on Special Report #3 now and I'm really excited about what that's going to reveal. The things Land Matters can do with our huge databases is truly amazing. I'll have more info on that report when we get closer to releasing it.

I've added the Sage Grouse proposed Mineral Withdrawal display to the Mining Claims Maps for the five affected states. It's a separate layer you will have to turn on to see.


This map has been heavily requested. Check it out while you can since the BLM is known for disappearing maps without notice.


This map was not easy to find. It's not going to be easy to use either because the BLM is serving it up in a light dirt color that blends with just about every base map layer. Now is a good time to learn to use the transparency tool found by right clicking the layer you want to change the transparency on.


The affected States Mining Claim Maps are linked here:












Here's the description of the Map information from the BLM. As you can see the map isn't accurate because the boundaries of the final withdrawal won't be decided until after it's passed. :BangHead:


The areas recommended for locatable mineral withdrawal dataset were compiled from the Bureau of Land Management (BLM) National Greater Sage-Grouse (GRSG) Conservation Strategy, which includes Environmental Impact Statements (EIS) for the revision or amendment of 98 Forest Service and BLM land use plans. Data reflect the areas of Sagebrush Focal Areas, a subset of GRSG Priority Habitat Management Areas, which are recommended for withdrawal from the Mining Law of 1872 in the Records of Decisions for the Approved Resource Management Plans and Amendments.


DISCLAIMER: No warranty is made by the BLM or FS for the use of this data. The GIS data included on this page is intended for broad planning purposes only and should not be solely relied upon for any decision making. Accuracy of the GIS is limited to the accuracy of the data available to create these layers at the time of this project. The information contained on the map is used to generally locate and identify the lands that are proposed for withdrawal in the sage brush focal areas and is for reference purposes only. They should not be construed or used as legal descriptions. Detailed maps and legal descriptions will be developed at a later date.


We are trying to figure out a way to get a list of the affected claims from this information. If we succeed we will make a list and share it on the Land Matters website.


Please pass these maps around. It's your Land and it Matters.

As many of you know Land Matters updates their free online mining claims maps twice a month.


Normally we get updates from the BLM servers in Denver on the 2nd and the 16th of each month. We just received word today that the BLM has been having difficulty with their database updates for the last month or two and now it's affecting their partner delivery system. Best estimate right now is we will see updates by end of day tomorrow January 6th.


If you were wondering when the claims map update is coming or when the Claims Advantage Member reports will be available now you know. We will bring those updates to you as soon as we have the information.
