Rainbows require two things: sunlight, and water. Rainbows can be seen not just in the rain but also in the mist, spray, fog, and dew.
The best place to consistently find both of these things and spot a complete rainbow, is a tall mountain or ridge where it is or has just rained, making the Adirondack high peaks an amazing place to view this natural wonder. A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. Similar to a mirage, a rainbow is formed when light rays bend, creating an effect that is visible, but not able to be touched or approached.
