At 357 feet tall and 26 miles away and an eye height of 5 feet you get 360 fee of curvature. It's not possible even though you can see it. Earth is either flat or, they are lying to us about the curvature math. It's eight inches per a mile squared. Do the math. You'll see I'm correct. Many people can see the Farallons from Ocean beach on a sunny day. Even if you're standing 10 feet above sea level, that's about 30 feet of island you should be able to see, but we see much more than that. Try to prove me wrong. You won't be able to. <br />Anonymoushttps://www.blogger.com/profile/01382774296289656779noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-91754430844960858782017-01-09T08:17:16.875-08:002017-01-09T08:17:16.875-08:00"A.

But as that article points out, "A simple approximation is to consider that a mountain's apparent altitude at your eye (in degrees) will exceed its true altitude by its distance in kilometers divided by 1500." (Assuming normal temperature and pressure.) Since the islands are 43 km away, the apparent height will be 43/1500 = 0.028, or about 28 meters, which I feel okay about ignoring.<br /><br />Good point, though.
