Mauna Loa Hovering!
Walking the caldera you are a bit below 4,000 feet
altitude above sea level and there looming in the distance
(if you are fortunate enough to have a clear day) is
Mauna Loa (a bit below 14,000 feet). If you have read my
Mauna Loa disertation on the caldera page, you might now agree
with me that it is difficult to see where all those other 10,000
feet are hiding.
Nonetheless, it is a wonderful sight and a wonderful day to
be alive. As you hear the hollow crust crumble beneath your
sneakers, you try to tread lightly hoping to extend the feeling
for another day.
Note the markers here warning you clear of the pressure rubble.
