An early day for Cal up at 2:30 am to prepare for a ride to the top (10,000 feet) of Haleakala Peak to watch the sun rise over the volcano crater. It was very cold on top of the mountain - very cold. Fortunately, Cal had read about the chill and was prepared, but there were others on the excursion in shorts - it was below 40 degrees and very windy.

We arrived well before the sun was up - and to be "up" it will have to crest the clouds as the summit was higher than the cloud cover.

The sun is "up" but not over the clouds creating a very colorful sky and glow off the clouds.

The sun finally (about 40 minutes after "sunrise") peeks over the clouds.

The moment the crowd (estimated to be greater than 400 people by our guide) is waiting for. Fortunately we were the first up to the top and have great spots to watch the beautiful display.

The sun touches the crater side lighting volcanic cones.

At the summit in front of us is a vast crater seven and a half miles long by two and a half miles wide, and 3,000 feet deep. It last erupted in 1790 and has slumbered ever since.

The endemic Silversword is a distinctive plant of Haleakala since it grows nowhere else on Earth. Climate change has been threatening the population of this plant due to hotter temperatures and lower rainfall. Placed as endangered in 1992 it has made some recovery due to strict management and fences.

The plant on the left is dying after sending up a flower stalk for seeds. The plant on the right is younger.

After lunch we went out on a whale-watching cruise. Unfortunately the sun was out and we kept spotting whales into the sun, which made for poor pictures. Additionally, the boat was big with a good 60 people on board which made it hard to maneuver quickly and close on the whales.

The most spotting was of the blowing of water while they breathed.

Then we all watched for the tail as the humpback whales headed back into the depths.

Every year, over 10,000 humpback whales migrate to Maui's protected water to mate and give birth.

An interesting activity was underwater hydrophones to hear whale songs. The sounds were amazing - from the whales all around us.

We then spotted two humpbacks moving away (of course) from the boat at a great distance. One on the left is breathing and the one on the right is about to dive.

Everyone was excited when we spotted the pectoral fin of a humpback.

The humpback's pectoral fin is longer than that of all other species of whales, measuring one-third the whale's body length, or approximately twelve to fifteen feet.

Humpbacks will often roll onto their side or back and slowly slap the water's surface with one fin or both fins simultaneously. The slapping of fins may serve as a communication signal to other whales.
