Important things about this website

Stereo images are more than an important part of my website, the third dimension contains vastly more information than a flat image. Many features blend in with the background and cannot be appreciated in a two-dimensional view. Images on a computer monitor are fixed so you can't "wall-eye" them like a field geologist does with pair of paper prints. In order to see computer stereo, you have to cross your eyes like you did when you were a kid. For some people this is easy and for others very difficult. I beg you, try. I have gone to great effort to provide these stereo images.

Imagine a line straight out from the center of the screen. Position your face so that imaginary line passes between your eyes. Cross your eyes so that you see four blurry images on the screen. Move your head and eyes around to fuse them into three, the middle being the overlapped right and left. With any kind of luck, depth will suddenly jump out of the middle image as your eyes focus on the screen.

If you are having difficulty, go to this website for some simple photos that are easy to view. There's a whole bunch of stuff on the web about how to view stereo.

SCALE

Science uses the Metric system. The web is full of sites that convert, should you need it. As an air navigator, I flew nautical miles and navigated in minutes. Now, I report locations in decimal degrees. 111 m is a milli-degree and 11.1 cm is a micro-degree (3 and 6 places, respectively). The hand-held GPS unit has an accuracy of 5 m, (5E-5 deg). Both your GPS and Google Earth will display positions with 9 to 11 figures, they're lies. mm and gray cards
