Apparent horizon or visible horizon. The line where the earth meets sky.
We’ve got plenty of buildings and trees that block the clean line around here.
First up – Coney Island Horizon
Another clean line separating earth and sky in Cumberland Ohio at The Wilds
Charleston West Virginia Horizon
New York City Horizon
And a vertical taken in traffic at the red light Pittsburgh PA
Okay, that’s a pretty good sampling of horizons.
Starting to get too many choices to put up. I’m stopping now and going to bed. I thought about going into an external hard drive and finding British Columbia or Okanogan WA but it’s late.
