UPDATE: I’ve posted a more comprehensive set of resources for free topo maps for Garmin GPS receivers.
Above the Timber is about to release DVD’s of 1:24,000 scale topo maps of the Colorado Rockies for Garmin GPS receivers. I call them 1:24K scale maps even though that is a bit of a misnomer. These are digital maps, so the scale changes at each zoom level. However, the data on the screen is based on USGS 1:24,000 scale topo maps, and they show 40 foot contour intervals, as seen in the image shown here.
The Colorado Topo Maps DVD will go on sale around May 1, at a special introductory price of $79.95. While you can “make your own maps,” the process is a bit laborious, so if you are a back country enthusiast in Colorado, this is a pretty good deal.
