A "Glitter Path" occurs as the sun, or some other source of light, is reflected across a body of water. Ripples and waves upon the water cause the reflection to become distorted and elongated. Other objects can also reflect the sun's image and continue the path, as in this photograph.
In this photo, taken from my cell phone, the setting sun is first reflected off the glass windows of a building located along the eastern bank of the Elizabeth River in Norfolk, Virginia. You can see a small bit of a glitter path reflected in the river just below the building. The reflection is then continued across the open mini blinds in a window of the Naval Hospital which is located on the west bank of the river in Portsmouth, Virginia.
