Today I put a GMap link onto the front page as suggested by Fred Touche months ago. This will allow you to quickly bring up a GMap around any given point. For example, if you are looking at Google Earth and want to see one of the Bivouac maps around the same area. I use it if somebody sends me the lat-long of a missing peak.

In order to keep search engines out, the link is only visible to paid subscribers. There is also a link in the index.
