Trees are critical to moisture extraction throughout the year, with the results being most evident and majestic during rime formation when the actual captured product becomes clearly visible for everyone to see.

While many bare trees are featured in the high country as this final month of meteorological autumn begins, pockets of color remain and 
leaf coverage is much greater than usual.

For three consecutive weekends snow flakes flew atop the High Knob Massif, with this third weekend marking the first, actual accumulation of snow and rime at highest elevations.

Accumulation was short-lived, with significant melting by around 1130 hours (11:30 AM ) when Layton captured these beautiful scenes.

All snow and rime was nearly gone by Noon, save for a couple inches which had blown up against the Lookout Tower (*).

*Some kids were making the first 
snow balls of the season out of that!

Air temps climbed to around freezing by 1120 hours, even on northern exposed slopes; although, a little bit of snow-rime did linger through 1500 hours on Eagle Knob (36 degrees at 3 PM).
