24K Topo

Now that I'm moving to an area that is covered by this mapping, it's worth purchasing. Previously it just didn't cover an area that I hiked in. Having this detailed info it great.

Great product for Garmin GPS hikers

Excellent product if you hike in one of the areas covered by this electronic map. Contrary to the name, it covers much more than just National Parks. It covers many National Forests and State Parks as well. Just check the coverage against your area of interest and if you have a match, it is well worth the purchase.

Inferior product

I was forced to purchase this since it is the only product usable for hiking trails which can upload to my GPS unit. However my initial impression viewing the maps on the computer screen is very disappointing. At least in Big South Fork where I am planning a trip, the trails are very incomplete. The ones which are present are very difficult to see in dotted grey on a white back ground. They do not contrast well with the road (solid grey) and jeep trails (hatched grey) or the contour lines (brown). The only use of color is blue for streams. ^M
