glaciers continued in 2008 as well, though<br />
we could say something like “better than<br />
worse”. Coming from years that were anticipating<br />
the glaciological and climatic scenarios<br />
predicted for the end of XXI century,<br />
this might be of some satisfaction.<br />
During the 2008 Glaciological Survey, 96 glaciers were subjected to a complete glaciological<br />
survey 1 (36,5% of existing glaciers); their combined area was 9061,4 ha or 83,6% of Lombardy<br />
glacialized surface. Adding the photographic observations2 (103) the number of glacial apparatuses,<br />
inclusive of both glaciers and glacierettes, increases to 199 (75,7 % of all glacial bodies<br />
or 95,4 % of the entire regional glacial area).<br />

1 Complete glaciological survey means that a detailed on-site investigation was performed by the designated<br />
operators; where possible, their evaluation included: snow line altitude, minimum altitude of the front, front<br />
measurements. Operators also remarked the morphologies variations versus the previous survey.<br />
2 Photographic observation means that a glacier is investigated through one or more photos taken from<br />
selected photographic stations to allow meaningful comparisons over the years. Such observations do not<br />
provide dynamic indexes.
