I'm sure there's some effect but never having used a sextant "uphill" I have no idea.

But atmospheric effects, mainly localized heating and flows of air masses, may prevent you from getting a fix better than 2 miles. So if you get that close--don't bang your head, it may simply be as good as it will get. (The same problem applies in coastal use of a sextant.)
