If you're looking for photographs of caves for personal or editorial use, you've come to the right place! My images of caves have been published internationally in books, magazines, and calenders, and been displayed at museums, including the Smithsonian. My collection draws from over 40 years of cave photography in caves of all types from around the world. Collections of some of my best photos are available on CD-ROM on this site. These are sold for personal use only. If you need cave images for editorial or commercial use, or have a need for a particular type of cave photograph, please contact me via e-mail. To get an idea of the range of images I have, view some of the sample images for the various CDs, watch the slide show, and/or visit my top-rated educational site on caves and cave formations, the VIRTUAL CAVE.

I will also do cave photography on assignment, whether in remote wild caves, or especially, for show caves. Some of my most recent work has been for Mercer Caverns.

Calaveras Natural Bridge Postcard Sets

Only two prior postcards existed of this star Calaveras County attraction, in 1908 and 1910. With a rich body of my own work there, I created this set of 10 different postcards as shown below. Click on a thumbnail for a larger view. Note the copyright overprints don't appear on the printed cards. They are a standard 4x6 size on glossy card stock. You can buy them individually from me at caving events or from Calaveras County vendors including Mercer Caverns, the Angels Camp Visitors Bureau, and Turners Wild West. If other vendors are interested in purchasing any at wholesale cost for resale, please contact me. Via mail order, they are only available in the full set of 10 for $5.00 (or multiples of individual cards that add up to 10).

5. The Virtual Cave Screensaver/ Slide Show
(click for more info and a 20-slide sample portion of the show)

The Virtual Cave is an award-winning website devoted to caves and their wonders. This CD contains a screensaver and slide show for Windows-based systems that presents a tour through an idealized cave. The tour begins with descents down a series of shafts and then traverses through various types of cave passages. Then it highlights different varieties of cave formations from all over the world, using some of the images found on the Virtual Cave and more. All the major types of cave formations are represented. The base resolution of the images is 1280x1024, but they will scale well to whatever screen resolution you use (they even look good on my 30-inch monitor running at 2560 x1600). The show comprises 200 different images. In the Slide Show, small captions indicate what type of cave formation you're looking at, and you advance the images manually. Along with the Virtual Cave website, a great presentation tool for educators.

The next best thing to actually being there!

6. Black Chasm: Jewel of the Mother Lode
(click for samples)

Black Chasm Cavern is a show cave near Volcano, California, in the heart of the gold rush area known as the Mother Lode. It was designated a National Natural Landmark for its world-class display of helictites, a type of cave formation whose growth defies gravity, twisting and turning in random direction. Those in Black Chasm are clear as glass. In addition there are unusual spar formations, including hexagonal spar, which has not been documented in any other cave, and seen on the CD. Another hallmark of the cave are its deep, blue lakes which are highlighted in the images with submerged lights. On this disk, I present 150 images that show the beauty of this unique cave both on and off trail. There is an annotated slide show and a Windows screensaver, which is copied into the Windows directory and is displayed during idle time on the computer. There are also 12 images for use as snazzy Desktop backgrounds or "wallpaper."
