Track weekly lava changes at a volcano with this helicopter diary

Mick Kalber of Paradise Helicopters takes tourists and photographers up over Pu'u 'O'o's lava lake and other remarkable lava flows each week. For those of us who can go up each week with him, he shares a weekly diary of his favorite moments.

Last year he even spotted this delightful smiley face in an active lake.

Here's the Paradise Helicopters site if a trip sounds like fun.
