Yellow is BLM land, blue is state, white is private, other colors are forest, reservations, military, parks, etc. Very useful when boondocking. The state parcels are 1 mile square, left over from the old railroad land grabs. If there is sufficient interest, I'll rescan these to their original dpi, which is double what you see here. Not available for Oregon or Washington. Historically, these maps were available by county, but were discontinued.

Each state highway map is proivded by different companies and have differing resolutions and features. All these maps are available free in paper form from each state's visitor centers or by mail. DPI was reduced from the originals.

Topographic maps at state scale. These are attractive because the map features are predominately things you can see. However, major highways are not nearly as clear as you would expect.

USGS standard digital raster graphic. Files are compressed in row-ordered packbits, very fast when used in Oziexplorer and nearly optimal compression. The elevation rings at the bottom of this segment represent a magnificient volcano.

Ditto above. Having both 250K and 100K maps is an advantage, not only because of scale, but many of the included features are different, such as archeo-logical sites.

Ditto above. These are hiking maps. I can't help but observe that I spent a lot of child-hood days in the pool at the SE corner of this map segment, fed by a hot spring and located at the bottom of a volcanic gorge.
