I posted earlier about a set of high-res topo maps (roughly equivalent to 1:24K USGS topos) for Wyoming and Colorado; the comparable maps for Utah have just been released:
- Interstates, highways, railroads, county, local and forest roads
- High resolution water data (lakes, rivers and streams)
- Land use, metro areas
- Elevation contours (40ft intervals)
- Points of interest (summits, mines, falls, dams, cemeteries, towers, populated places, etc.
Via GPS Tracklog and the encyclopedic GPSInformation.Net site.
He has also released an updated version of the Colorado map including high resolution water data.
