The day dawned a bit cloudy and overcast but by nine in the morning the sky was blue, the hills jurassic green and the waters holocene blue. Cumulonimbus, silvery, floated across the lake as father and I climbed higher and higher in up the mountainside of Samosir Island. It was just another glorious, priceless and perfect day at Lake Toba. And then a photo comes along and just absolutely steals the show.

I confess I was a touch worried the monsoon season would bring bad weather. But the temperature is perfect and the Bataks as friendly and kind as ever, children, old men and women all shouting, "horas" to father and I as we zoomed further up the mountain side.

It was just one of those days that Lake Toba produces. Perfect in almost every way.

Today's photo can be found beginning here and moving forward. The full set, as always, can be found here.
