lauterbrunnen, and other large European walls.
if anyone can help me here, It would be great. I have a large project in the works and i need information on the dimensions and various other characteristics of HUGE walls in Europe. in the US, we have the USGS (US Geological Survey) but even for the walls here that is not enough. I have visited all the walls here, but sadly have not jumped internationally.
what i'm looking for is distances and wall shapes, from exit to impact (rock drop impact as well as very poor/basic tracking impact heights). Just as important, I need the shape of the upper ridge exit points, and their relative placements. google earth is almost as useless as USGS maps, so i need either aerial photos, or someone with intimate knoledge of the areas. Lauterbrunnen is my first target, as from pictures and video i have seen it seems the most interesting.
any help? anyone have very good topographical maps of these cliffs? websites?
thanks for the help...
