Couldn't get a picture, but over the weekend I saw two disused aerial ropeways that crossed the international frontier between the USA and Mexico. Can send written informartion about the one at Boquillas (Silver and Fluorspar) to anyone interested. The other, just east of Presidio, TX, I have seen never seen mentioned. I will also have photos (touch wood) in a couple of days of one of the Mercury mines near Terlingua, TX, and of the Silver mining ghost town of Shafter, TX, if anyone is interested. Can send references on Terlingua. Would be interested if any of the N. American members of the list have references to the geology of either mining district - I think there's some TX BEG stuff on Terlingua, but most work was proprietary. Both districts are some sort of replacement or open-space filling in limestone: plenty of igneous activity in the district, but no obvious source of the hot waters. The mercury deposits are pre-large scale faulting, and I have a book that te!
lls the story of the geologic inference used to find the off-set portions, but the book is by a historian and contains no maps or cross-sections. Apparently Goldfields controlled Shafter until 2 years ago. John Berry

Aerial ropeway with a difference on
www.users.globalnet.co.uk/~mccamley/main-east.htm at Monckton Farleigh mine
which was used as a munitions dump. Download takes about 5 minutes for a
50second video of working system.There also used to be an aerial ropeway in
north Kent at Bowaters Papermill Kemsley Sittingbourne, it ran about 3
miles to the docks at Ridham and was used for carrying pulp and pulpwood.I
think it went out of use in the 70s but as far as I can remember is still
in situ. It should be visible from the A249 at Kingsferry bridge onto the
Isle of Sheppey. Pete
