On the trail at Haleakala!



When I get in the mood for a vacation, I grab my pack and head off to another island. A couple of years ago, I had the opportunity to hike Haleakala volcano, on the island of Maui. Haleakala is one of the most spectacular places I have ever been. The scenery is absolutely breathtaking! Check out the Haleakala National Park website for more information.

Reticulite: An extreme form of pumice!


Reticulite is an extreme form of pumice formed within high lava fountains; about 1,000 feet, (300 meters), high, or more. Dissolved gasses within the lava form bubbles which expand until they burst, leaving behind a fragile,  honeycomb - like structure. In spite of its light weight, reticulite does not float. Drop a piece of reticulite in some water and it will sink much like chicken wire.

The Corpse Flower

Amorphophallus titanum, or the Corpse Flower is a rare native of Borneo. The specimen shown here, at the Panaewa Zoo in Hilo, is on loan from a private collector. I had the good fortune to be at the zoo to see it blooming, and to smell its pungent fragrance. It kind of smells like roadkill. In addition to its unique smell, the Corpse Flower also has the distinction of being the world's largest unbranched flowering plant.
