			How can the Moon rise through a mountain?  
It cannot -- what was 
photographed here is a 
moonrise through the 
shadow of a large 
volcano.  
The volcano is Mauna Kea, 
Hawai'i,
USA,
a frequent spot for 
spectacular 
photographs 
since 
it 
is 
arguably 
the 
premier 
observing 
location 
on 
planet 
Earth.
The Sun has just set in the 
opposite direction, 
behind the camera.
Additionally, the 
Moon has just passed full 
phase -- were it precisely at 
full phase it would rise, possibly 
eclipsed, at the very peak of the shadow.
Refraction of moonlight through the 
Earth's atmosphere makes the Moon appear slightly oval.  
Cinder cones from old volcanic eruptions are visible 
in the foreground.
Cloud tops below 
Mauna Kea's summit 
have unusually flat tops, 
indicating a decrease in 
air moisture that frequently keeps the air unusually dry, 
another attribute of this 
stellar observing site.
