Spring Snow on the BigHorns

It’s green spring grass contrasted with Snow on the 130 mile distant peaks. This image is taken from my driveway here on the MT/WY border. Clearly “Nipple” butte stands 10 miles distant. The treed ridge is 40 miles out with the trees at the top of that ridge being the same elevation I stand/live. The 13000 foot high peaks of the Bighorn Mountain Chain reach far above that but well over the curvature of the horizon at it’s base. . Even further out than the range the bank of clouds stands perhaps 200 miles out from my camera.

Anything over 100 miles is a long photograph. Particularly through the low earth’s atmosphere. It take extraordinarily clear air to get detailed images of the Bighorn Mountains from this distance. To get images of the clouds well past it… That is a silly far shot. Now I take images of astronomical objects millions of miles away but only through 300 miles of atmosphere. MOST of that atmosphere is in the bottom 10 miles of the blanket. About equivalent to where Nipple Butte is….

TO find the distance to your “horizon, take the height of above the surface of your view point divide that by 0.5736 , then take the square root of that number and you have the distance to the horizon from your viewpoint. If your 6 feet tall the horizon is about 3 miles away. Works very well on flat ground… up here where there might be a few ridges around, it depends on topography too lolol.
