NOTE: This item has been discontinued by Garmin. It is replaced by MapSource Topo U.S. 2008 (click here), with updated maps and features condensed onto a single DVD-ROM.!

Plan your next outdoor adventure with the help of MapSource United States TOPO CD-ROM.

Highways, roads, hiking trails, snowmobile trails, backwoods trails, elevation contours, point elevations, summits, some bathymetric contours, geographic names, churches, and schools

Shoreline detail for lakes, reservoirs, small bodies of water, waterways, rivers, and streams

Icons representing boat ramps, dams, marinas, campgrounds, public facilities, mile markers, first-aid stations, picnic, swimming, and ski areas, wrecks, fuel, and dangerous and restricted areas

Nautical navaids for the 50 states including radiobeacons, RACONs, and fog signals; river, harbor, and other lights; and daybeacons and lighted and unlighted buoys

Wrecks and obstructions—such as shipwrecks, submerged rocks, obstructions, and other hazards to nautical navigation
