There is no physical cache container to find or logbook to sign.
What you do for this is go to the location and stand in view of the camera, so a picture of you is broadcast on the Internet.
Then get a friend to capture the picture to a file, and upload the picture with your log to show you were there.
Here's how people generally work webcams:
The first thing to do is to team up with a friend who can be at a computer looking at the Mono Lake / Lee Vining Webcam image at (
visit link) in a browser.
ADDED NOTE 12/28/08 - UNFORTUNATELY, you now have to "Register" on the webcam site to get the photo of a size that would be useful. Your call if you want to do it.
It will be easier if both of you take a look at the site and the webcam page ahead of time to see what the area looks like where you need to stand.
Next, go to the posted coordinates. They are about as close to center of the camera’s field of view as you can get across the street from the camera.
Stand where the camera gets a recognizable picture of you. On the sidewalk is a good spot and close enough for a good image. The camera displays a new image about once every five minutes so you may have to wait a bit for your friend to tell you you're in the picture.
Here are some suggested guidelines for a picture that shows it's a picture of you the geocacher, not just some random screen shot:
-Face the camera and look straight at it. That alone will distinguish you from people who are just looking at all the Stuff.
-Make some distinctive gesture, which will most likely be holding a cell phone to your ear as in the sample pictures. Or if you like you could hold up your GPSr or wave to the camera.
-When the web page is showing a good image of you, your friend should save a copy of it. In most Windows web browsers, that's one of the options from a right-click on the image. You may like to practice this ahead of time.
-Have your friend get the saved image file to you somehow, maybe as an e-mail attachment. Log your cache visit, then upload the image file as an addition to your log.
All the above are simply suggestions of likely ways to get this to work. If you happen to have a web enabled PDA that you can use to capture the webcam image by yourself without a friend's help, or creative ideas about posing in a recognizable way, go for it. This is about having fun!
