Alpenglow such as this occurs when there is a LOT of ice in the atmosphere mostly during winter. . I’ve also seen smoke do this kind of scene in the summer. Here on the high ridges of the borderlands, I get to look at parallel ridge tops like this 40 miles away to the east.
After passing through a gauntlet of filters in the atmosphere, crimson/orange/yellow are the survivor hues. Absorbed/blocked/refracted away are the shorter wavelengths of color. Can’t trap them in my photon capture boxes (cameras) if they don’t make it to me. Passing that gauntlet to blues/greens and indigos consists not only of hundreds of miles of low angle atmosphere plus all the dust and the dirt suspended within.
The sun isn’t actually occupying the line of site where it appears to be here. Because of atmospheric “lensing”, the sun is actually still completely below your eye to the horizons line of sight. It just looks like it’s up. This accounts for several minutes of differences from rise/set charts versus the observed sunrise with the day always being longer due to lensing. The atmosphere literally bends it’s light around the curvature of the earth thus the “lens” part of atmospheric lens. This courtesy of inversions and thermal-clines. The path this light took was at least 300 miles of low angle air. The higher I go topographically, the longer the light I gets path. The redder the alpenglow.
In taking this image Pink “Belt of Venus” Alpenglow Crack of Dawn on the “Red Hills”, I was at around the same elevation as the saddle to the left of the peak off in the “Red Hills” 40 miles away from the camera.
I wonder why they call them the “Red Hills”? hummm.🤔
The Science of this.
The Light Stuff: The Pink Alpenglow known as “The Belt of Venus” is literally the back show of a sunrise over my shoulder that was s a stunning clear sky yellow Alpenglow scene saturated by an orange and yellow gradient sunrise THROUGH the atmospheric ice present. You’ve seen other photos of that in the wetlands around here just recently posted this morning perhaps elsewhere. This is the back show where only the longer more penetrative red/pink rays of light make it through to the relatively light grey atmospheric ice present and reflects even more red. The red rocks on the hills are also adding to the effect of just the tip of the Mountain is exposed to the sun over the shadow of the horizon behind me. Technically the sun has risen for some places and not for others.
Geology: That is the Little Powder River Valley with the Montana/Wyoming border somewhere in there. That little 6 foot wide river removed all the sediment between here and those mountains all by itself. No kidding. I wonder how long that took a spring flood and yearly freeze thaw cycles to break up the bedrock so the river can haul sand/silt/clay most of the time? 🤔 Cobbles only move during floods. Quartz cobbles are common down in the river valley where they eventually make their way. Being harder they resist erosion, being heavy, they don’t travel very fast and tend to concentrate in the river down there. Quartzite cobbles up here in pure fine grained sandstone country are rare. When I find them, they are affiliated with Dinosaur Bone Deposits and are probably “gastroliths” or stomach stones (like chickens swallowing gravel). Dinosaurs moved literally small boulders around in their stomachs and left them here mixed in randomly where you find dinosaur bones. the same river concentrated both just like it does gold.
This has been an alpenglow day……3 posts in a row anyway… Change up is in order I think📸
I was fighting Dew on the lens with this Pink “Belt of Venus” RIGHT at the Crack of Dawn. THere was a lot of dew on the grass and the light was very pink/red that morning. A side show to the sunrise ongoing to my left. Never forget to turn around lol.
I work well over 400 sunrises or sunsets a year these days. Some I miss, others I choose not to pursue. I’ve been known to sleep through a few rises but I don’t miss many sunsets. Just clouds in the way slow me down a bit. Grey flat light and I are like matter and anti-matter lolol.
This is as close to the Crack of Dawn as I can get and still see anything more than a pinpoint of that big ball o fire. BTW….Pointing a normal DSLR camera into the sun is a bad idea if you don’t want to blind yourself. I use mirrorless cameras and more or less watch what I’m looking at with long big lenses on a little TV screen inside the eye viewer of the camera.
This was an unusually good sunrise that morning. I typically photograph most of civil twilight through the hour after the sunrise (golden hour). Mostly I photograph both sunrise and sunset shooting many hundreds a year usually over 400 a year historically. I’ve taken 57000 images since August 1. Looked at them all, finished around 6 a day average this month. It’s good to be busy😁
