The imaged forms on the horizon are the bodies of the Hawaiian islands of Lanai and Molokai. But from high in the sky I erased a tiny image of a drone peering down at them.
Sandy Beach, Oahu, Hawaii, December 1, 2020. The other islands visible are, from left to right, long low Molokai with Lanai rising behind it, and (low on the horizon to the right of the cloud and about 100 miles distant) Maui, with its 10,000-foot volcano, Haleakala. Click to enlarge.
