Some weekend cave exploration

Posting today shall be very quiet, mostly because I am out in West Virginia, exploring a previously unknown upper level in a cave we are mapping. This passage was only discovered last month by Aaron Moses, John Harman, and Pete Johnson, who did a bolt climb of over 70 feet to reach a high lead in the wall of the cave. This weekend we will be pushing and mapping these virgin passages. Below is a picture taken by Brian Masney of Aaron Moses as he worked his way up the wall, with Pete Johnson providing a belay. More of Brian’s pictures can be seen on his Flicker webpage.

More cave images from the Moon

James Fincannon of NASA has forwarded me two additional pictures of the same cave on the Moon, taken recently at different times by the camera on Lunar Reconnaissance Orbiter and made available by the Goddard Space Flight Center and Arizona State University.

These images clearly show that the skylight looks down into a much larger space, with the underground room belling out from the skylight in all directions. This can be seen by how the angle of sunlight hitting the floor of the cave changes over time. Below is a very crude cartoon I have drawn to illustrate what I think we are seeing in the image on the left. The dashed lines indicate unseen walls whose precise location is not yet determined.

James also forwarded me this link, showing even more images of additional lava tube skylights on the Moon.

Caving July 10, 2010

I was out in West Virginia this weekend for the monthly gathering of the Germany Valley Karst Survey. This project has discovered and mapped more than 37 miles of virgin cave passage in West Virginia in the past eight years. For the last two years I, along with about a dozen other project members, have been focused on a dig in a small cave that has the potential to break out into a lot of virgin passage. Below are two pictures taken by fellow caver Daniel Martinez, the first showing me at the cave entrance and the second showing my feet as crawl in.
