78) “From Anchorage, Alaska at an elevation of 102 feet, on clear days Mount Foraker can be seen with the naked eye 120 miles away. If Earth were a ball 25,000 miles in circumference, Mount Foraker’s 17,400 summit should be leaning back away from the observer covered by 7,719 feet of curved Earth. In reality, however, the entire mountain can be quite easily seen standing straight from base to summit.”

 

 

 First, there's a very clear superior mirage in that image - the foot of the mountain is not visible, but there is a different colour there (etcetera).

Also, it happens quite often there - the latitude and the geography combine to regularly cause mirages, e.g. the 
Eleutian range is often visible.

As for the angle, we've already discussed it. It's not much, although this height should be resolvable. Now, I'm not familiar with these mountains, and mountains are known for having so many ridges and angles that I really can't tell if it's straight up or tilted. 



False claim.
Mount Foraker has an elevation of 5304m. Distance to Anchorage is 210km. Even factoring out refraction, the horizon for Mount Foraker lies at least at 260km.
