Must be rare to get such a reflection of the sky in a calm Tidal Basin pool; from the Department of Interior‘s Instagram:
From Interior’s Instagram: Last night we posted an aerial photo of the #Washington #Monument, which everyone seems to really enjoy. So we are keeping it going today with a #photo of the #Jefferson #Memorial. #NationalMall #DC
One commenter noted the photo almost makes it appear that the Jefferson Memorial is floating in the clouds.
There are more than 300 units in the National Parks System. In the past two days we’ve had two spectacular photos from almost the same place, two memorials about a half-mile apart. How many thousands of great photos are possible from all of these properties? NPS’s job, caring for all of that stuff, is monumental.
