Our site is www.barranquismo.sitio.net We are working in a world-wide data base of canyons.
We want to collect in a single page all the data about each canyon. We have some books but
we need many and we would like to receive aid to be able to do it. In
this site http://www.iespana.es/barranquismo/B...osdelibros.htm
You can see the books that we do not have. If you have some
of them, we would like to receive index and, if it is possible, the
image of the cover. In this page you can see the result of our work until
A greeting and thank you very much by your
