2008 glaciological<br />
Survey<br />
Tab. 5: the list of glaciers surveyed in 2008 and the comparison with their previous surveys. Also indicated<br />
are: the front variation, the minimum altitude of the front (QMF), the snow line altitude, a brief note and the<br />
glaciological operators involved.<br />
Note: for the details of dynamic phases, see tab. 10 at the end of the chapter.<br />

Notes (Operators)<br />
Pizzo Ferrè DF -0,5 2698 irr.<br />
20% of total surface covered by residual snow; further thinning. (E. Congiu,<br />
S. Losa)<br />
<strong>Suretta</strong> S DL -22,5 2700 n.v.<br />
Mass balance measured with differential GPS, scarce residual snow cover<br />
(F. Villa, R. Scotti)<br />
Ponciagna DM n.v. thickness loss; residual snow cover almost absent (L. Colzani)<br />
Cima di Lago W DL N.M. n.v. recent snow cover, snow line not assessable, front shrinkage (L. Colzani)<br />
Codera/Masino<br />
Sivigia NE DM 2530 2850<br />
residual snow covering 15% of the surface, lower sector in a dismemberment<br />
phase (A. Barilli, L. Colzani)<br />
Passo di Bondo DL 3070<br />
snow cover only at the base of the rocky cliffs, moderate loss of thickness<br />
(M. Marzorati)<br />
Pioda S DM -16,5 2810 n.v.<br />
the link to the patch below 3064 m a.s.l. (CTR) has dissolved; snow cover<br />
hard to evaluate (G. Di Gallo)<br />
Disgrazia/Mallero<br />
residual snow cover under Sella di Pioda and at the base of the cliffs, the<br />
Predarossa DM -5 2625 3300 separation of upper and lower sectors is progressing (M. Urso, I. Bollati,<br />
D. Airoldi)<br />
Cassandra E DL -11,5 2915 3180<br />
good residual snow cover, strong thinning at the front. (R. Scotti, M. Fransci)<br />
Ventina DM -6,5 2222 2950<br />
irregular snow cover, though more consistent than in previous years; overall<br />
thinning of the tongue (M. E. Peroschi, F. Cambieri)<br />
Pizzo Ventina DL 2470 2650<br />
avalanche accumulations over the 40% of the surface (M. E. Peroschi, F.<br />
Cambieri, M. Urso, A, Almasio)<br />
Disgrazia DM -2 2610 2900<br />
more extensive snow cover in comparison with previous years, though<br />
insufficient to achieve an equilibrium balance (P. Pagliardi)<br />
Sissone DM -58 2600 2950<br />
strong withdrawal of the front and substantial morphologic variations in the<br />
lower part; snow cover over 40% of the surface (A. Almasio)<br />
Vazzeda DM N.M. 3000<br />
residual snow cover scarcer than nearby glaciers (A. Almasio, R. Scotti,<br />
M. Urso, I. Bollati, D. Airoldi)<br />

Scerscen Sup. DM 2750 3170<br />
thinning tongue; 155 cm of ice lost at 3100 m (A. Galluccio, M. Zambenedetti,<br />
P. Pagliardi, L. Colzani)<br />
Caspoggio DF N.M. n.v. dramatic mass loss, negligible snow cover (L. Colzani)<br />

Fellaria E DL N.M. 3450<br />
fairly good residual snow cover towards the Fellaria Plateau, evolution of<br />
the tongue with a remarkable widening of the proglacial lake (M. Butti, P.<br />

Pizzo Scalino DF -10 2620 ass. negligible snow cover; dramatic, overall thinning. (M. Butti)<br />
Dosde'/Piazzi<br />
Cardonnè DF 2530 3100 irregular snow cover, northern wall decaying (A. Galluccio, G. Cola)
