The first 2 pics are a Carlevaro-Savio lift, one of the mountain's originals
from when it was a private area. I believe it may have been one of the
covered doubles at one point (according to an old ski magazine). The chair
has been modified by ctec to a triple. Pictures 3,4 and 5 show the d triple.
The d triple was built by Von-Roll when they had taken over PHB/Hall
in the early 80's. The lifts were hall parts and designs from the Hall NY
headquarters. The company was purchased by and badged as Von Roll.
The 6th picture shows the F chair, another von Roll/hall and a ctec quad.
