On the same day as our whale-watching cruise (April 6), we took a submarine tour of Kailua Bay from Atlantis Adventures. The tour started at the Kailua pier, where a boat ferried us out to the submarine in the middle of the bay. The sub itself went down to around 80-90 feet by the end of the trip, and we got to see all kinds of fish and coral.
It didn’t look nearly so blue to us, of course, since our eyes were adjusted to it. Continue reading
One of the first tours we signed up for on Hawaii was a whale watching tour. We figured even if we didn’t see any whales, we’d still have spent a couple of hours on a sailboat. It was April, near the end of the season, and we booked a tour through Red Sail (via Travelocity) on their catamaran, the Noa Noa:
Kilauea is often called the world’s most active volcano. It’s been erupting continuously since 1983 at vents several miles away from the caldera. The eruptions are still inside Hawai‘i Volcanoes National Park, but the lava hasn’t stuck to the boundaries as it flows to the sea.
So late on an April afternoon, we started driving down Chain of Craters Road toward the ocean, hoping to see (from a safe distance) lava pouring into the ocean. The road is named because it connects a series of craters left behind by old vents. At first we stopped at all of them. They ranged from large craters like Keanakako‘i to fifty-foot-deep holes filled with rubble a dozen feet from the road. Soon we realized that would take way too much time, and stuck with the ones that looked particularly interesting.
I don’t recall which crater this one was at (probably either Puhimau or Pauahi), but there was a trail up to a wooden viewing platform. I stopped at one point along the trail and took this picture of a small tree on the edge of the crater.
Let’s see, when we left off, we had nearly completed a circuit around the Kilauea caldera. Before driving down Chain of Craters road to the coast, we stopped at the Thurston Lava Tube. Update (2021): The park is now emphasizing the Hawaiian name for the cave, Nāhuku, but at the time we visited in 2005, all the labels we saw still called it Thurston Lava Tube.
Lava tubes are formed when smooth a’a lava flows through a channel, then crusts over. The still-molten lava underneath keeps flowing until the source stops, and it drains out, leaving a long tubelike cave.
We were lucky in that there were very few other tourists there at the time. (It was the first week of April, which isn’t exactly the height of Hawaii’s tourist season.) The Thurston tube is famous partly because of its size, and partly because it’s very easy to get to. It’s less than a quarter-mile walk from the road.
Years ago, I put the Niven/Pournelle novel Footfall in my to-read box. I finally started reading it today. After a prologue that takes place mostly at the press conference for the 1980 Voyager 1 encounter with Saturn, the first chapter opens (years later) with a drive up Hawaii’s Kona coast and inland to the observatories at Mauna Kea.
Now there’s timing. If I’d read it when I first picked it up, I could only imagine that sequence. Now I know exactly what it looks like. Well, aside from the fact that there are twice as many observatories now as there were when the book was written.
