Observations On February 19, 2002, at 11:00 am, the group arrived at Mirror Lake where two ice core samples were taken. The same protocols were followed as at Cascade Lake.
ICE CORE SAMPLE FROM LAKE PLACID
Air Temperature (Digital #1)
2.5°C (original reading was 2.5°C)
Snow Covering
6-9cm
Location Latitude - 44.30N

Longitude - 73.98W

Observations Once the data were taken from Mirror Lake, the group traveled to Lake Placid where another core sample was extracted from the snow-covered ice using the same protocols.
Conclusions from Lake Ice:
From observing the core sample and ice blocks from Cascade Lake, our group noticed that there were two layers of ice from each sample. The top layer of the ice was composed of small crystals; it appeared very coarse and opaque. The bottom layer appeared to be very solid and of uniform consistency. It also transmitted light very easily. We determined that the top layer of the ice was snow ice. Snow ice is formed by water mixing with snow and refreezing. This could occur by snow followed by rain, or water from some other source. The bottom layer of the ice was lake ice, which is formed by the freezing of water contained in the lake.
