Ch Ch Cha Changes
Over the weekend we went for a hike at the Tahoe Meadows, it was windy and cold at the summit. We were shocked because it was warm and sunny down in Reno, perhaps the reason we were shocked was because we were still holding onto the belief that the weather hadn't really turned, but the cold pins and needles on our faces made us believers. After our hike we stopped by the lake, Tahoe that is. Crazily enough it was the first time we had been to the lake since being back in Nevada. I can't believe that we've been back almost a year and hadn't been back to the lake, especially during the summer months, although being at the ranch made it a little more difficult to head up on a whim.
The main cause of color change in leaves is day length or inversely the night length. The night getting longer and cooler is the trigger that signals the leaves to change. During the growing season or warm season, chlorophyll (which is the pigment that causes leaves to appear green) is continually being produced and broken down keeping the leaves green. When the day length shortens, the chlorophyll in the leaves is destroyed allowing the other pigments (carotenoid-yellow and orange and anthocyanins-red) in the leaves to show through.
The last change I'll discuss is that I have decided to post on Tuesdays and Thursdays at 9:00 am instead of on Mondays and Wednesdays. I tend to play on Sundays making it difficult to have a post ready by Monday morning. Sorry for any inconvenience.
