Michelle peers with trepidation into Luamakami--the snout of Hualalai. The shaft is dead vertical and you can't see the bottom. It's quite eerie. I threw several rocks down the hole and many seconds passed before the clink of rock on rock could be heard. But did my tossed rocks merely hit the side or did they hit the bottom? I'd say the hole is at least 150 feet deep. March 3, 2007.
