*cough*Google*cough* Garmin's United States TOPO MapSource CD-ROM is similar to U.S. Geological Survey 1:100,000-scale topographic paper maps. It includes trip and waypoint management functions that allow you to transfer waypoints, routes, and tracks between your PC and nearly all Garmin GPS units (excluding the GPS 100 family and panel-mount aviation units). With MapSource, you can view highways, roads, hiking trails, snowmobile trails, backwoods trails, elevation contours, point and summit elevations, some bathymetric contours, geographic names, churches, and schools. Shoreline detail is included for lakes, reservoirs, small bodies of water, waterways, rivers, and streams. Icons represent boat ramps, dams, marinas, campgrounds, public facilities, mile markers, first aid stations, picnic sites, swimming areas, ski areas, wrecks, fuel locations, and dangerous and restricted areas.

If so, could you let me know what the contour intervals are? I was looking online to possibly buy this for my new GPS and I see they are 1:100,000 maps, but I cannot find anything mentioning what the contour intervals are. The online map viewer seems to be set at something like 163 foot elevations and I wondered if the maps were the same. Thanks in advance. (yes, I tried to call, but they are closed for the day :))
