Did more editing this evening and realized that Starvation Resivoir in Utah was completly missing from the map. There is a POI for it, but the entire Reservoir and the major river feeding it are not on the map.

I am working through more updates in my county. The TIGER data has a lot of misaligned roads and additioanlly many National Forst main access roads were realigned and rebuilt in the last 5 to 10 years ago.
Today I also began adding businesses and other points of interst. I need to figure out how to locate via Lat/Long various sites as I have a large list of historical sites that are listed as Lat/Long.
I live in North Eastern Utah and started updating the the map in my area, there are a lot of major updates of just the roads that will likely take a month or so to get through.
One thing I noticed is the complete absense of BIA Indian lands on OSM. This become a legal issue for users of OSM on their GPS due to access restrictions. If you are caught on the Tribal land you will be arrested unless you can prove map error. Not having a map or GPS will result in at least a hefty fine. With total absense of these boundries on OSM, it is completely unusable in this part of the country by hikers, mountain bikers, campers, hunters, etc.
NationalAtlas.gov has shape files for BIA administered lands across the entire United States. How can I go about getting these into OSM format?
