Joseph, thanks so much for continuing to improve Gmap4. It sure is a good tool! And the availability of Matt's CalTopo maps is quite welcome, since MyTopo plastered their logo all over their online maps.

Fishmonger (and Joseph too, if you can do anything), that "Location Approx" of the Mt Whitney Mountaneer's Route is way off between Clyde Meadow and Iceberg Lake. I don't know how it ever showed up on the USGS maps, but people would get seriously in trouble if they followed it rather than looking up other maps.

Here's a link to Bob Rockwell's map, which is much closer to the actual route: http://www.flickr.com/photos/rockwellb/2767178079/sizes/o/in/photostream/

BTW, I made a donation, and encourage others to do the same. A free on-line mapping tool is nice, and having something we can use to include maps within posts here really helps illustrate topics.
