Maximum temperatures occurred during early afternoon, with local sunset having already occurred at High Knob Lake by 3:40 PM when this data was downloaded.

*Local sunset is defined as the time in which the sun drops beneath the mountain horizon, and during this low sun angle period of the year often occurs during early-mid afternoon in mountain valleys to significantly 
shorten the amount of insolational heating.

American Beaver activity has kicked into high gear during the past month, perhaps they can sense the major shift into winter upcoming for the mountain region.

*Sphagnum filled wetland valleys and a lack of logging are critical to maintaining this beautiful water that flows into Big Cherry Lake, the major water source for the mountain area.
