Hawaiian Catchfly; Silene hawaiiensis

While walking along the rim of Kilauea Caldera one day, I stumbled across this lovely, flowering Hawaiian Catchfly, Silene hawaiiensis. This plant is endemic to the island of Hawaii, and is considered to be a threatened species. This specimen is growing in a substrate of volcanic ash emitted during an explosive eruption of Halemaumau crater back in 1790.

Introducing Kevin Michael Connolly

Aloha everybody! I want to introduce you to my friend, Kevin Michael Connolly. I got to work with Kevin and Crew while they were here on the Big Island shooting a pilot for a new television show for the Discovery Channel. In the show, Kevin travels around the world, exploring the environment and overcoming obstacles. Oh, did I mention that Kevin has no legs? It was really amazing spending the day with Kevin, especially watching him moving around on the lava fields. I couldn't keep up with him! Check out Kevin's website to learn more about this amazing guy!

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.
