Observer, top, and bottom, form a triangle.


Angle that is made AT the observer is  {{{44-42=2}}} degrees.
Angle at the top of the face is  46 degrees.
Angle b at the bottom of the face makes for {{{b+46+2=180}}}, {{{b=132}}} degrees.


Length from observer to the top of the face on the mountain is  {{{600/cos(44)=834.1*feet}}}.


Use Law Of Sines to find the stone face, length from top to bottom.
