psi20 Posted February 22, 2005 Share Posted February 22, 2005 If you were stuck deep in the snow due to an avalanche or just slipping through and pointed a laser up, would it show on the snow's surface? Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 22, 2005 Share Posted February 22, 2005 Probably not. The snow would spread out the beam, making it nearly impossible to see at the surface. Link to comment Share on other sites More sharing options...
YT2095 Posted February 22, 2005 Share Posted February 22, 2005 more than a few inches (provided your hands were free to spit on to find out which way was up or not), it woiud no penetrate. radio tracker beacons are used instead, they WILL work up a couple of metres below the snow Link to comment Share on other sites More sharing options...
syntax252 Posted February 22, 2005 Share Posted February 22, 2005 Well I got one of those laser rangefinders for deer hunting and found out that if it is really foggy, or if it is raining hard or snowing hard, it doesn't work very well at all. It will give readings of about 25 to 50 yds regardless of what you are trying to range. Which, I assume, is the point at which the fog/rain/snow causes the laser to reflect back to the unit.

YT2095 Posted February 22, 2005 Share Posted February 22, 2005 now imagine that in densely packed snow I have a half watt laser here (and it`s been snowing) I shone mine through the bottom of a jar and added snow layer at a time, after about 8 inches (more or less) there was only a dull glow in a dim room at the surface. this has been tested and NO it`ll NOT work Link to comment Share on other sites More sharing options...
syntax252 Posted February 22, 2005 Share Posted February 22, 2005 Now, I suppose if it was a weapons grade laser, that might be different. I saw a demo on TV where they were poking holes through stel plates. I was impressed. Link to comment Share on other sites More sharing options...
Glider Posted February 23, 2005 Share Posted February 23, 2005 So, you're rescuers would just be looking for a tiny hole in a snow field? That'll help them Link to comment Share on other sites More sharing options...
Ophiolite Posted February 23, 2005 Share Posted February 23, 2005 Or they notice their steel toed safety shoes melting. Link to comment Share on other sites More sharing options...
RICHARDBATTY Posted February 23, 2005 Share Posted February 23, 2005 I would expect sound might be usefull. Although the satelite breaking orbit after using a high power laser would be very visible. Link to comment Share on other sites More sharing options...
swansont Posted February 23, 2005 Share Posted February 23, 2005 So, you're rescuers would just be looking for a tiny hole in a snow field? That'll help them Well, they're looking down, right. So when one yells, "Omigod! I'm blind!" you know you've found them. Link to comment Share on other sites More sharing options...
Gilded Posted February 23, 2005 Share Posted February 23, 2005 When U.S. completes their attack satellite array, the trick is to say very, very loudly (as you're under snow after all) "HEY, WHAT IF I'D COMMIT SOME TERRORISM TODAY!". The rescue team will have no trouble seeing where the ton weighing tungsten rod lands. Link to comment Share on other sites More sharing options...
Speaker Posted February 28, 2005 Share Posted February 28, 2005 Probably not, but it might help melt it. Link to comment Share on other sites More sharing options...
