Blue Haze at Blue Hour
It’s twilight (aka blue hour) and as the sun sets off to one side of the horizon, darkness begins to takeover, and a blue mist lingering over the valley becomes more visible.
This phenomenon is where the Blue Mountains receives it’s name, and is caused by the oil bearing eucalyptus trees releasing fine droplets of eucalyptus oil mixed with dust particles and water vapour.
Standing at a lookout in Wentworth Falls, off to the distance we can see Mount Solitary. It is surrounded by Jamison Valley to the left and Narrow Neck Plateau to the right.
