Early Morning BigHorn Light

This area of the sky is the size of your thumb at an arms length on the horizon. The BigHorn Mountains Cloud Cover that morning was climbing up the back of the peaks. Those clouds well past the 130 mile distant 13,000 feet high PreCambrian Cored, uplifted Mountain Range. Parts of Montana and Wyoming in this photo.

It was to cover the highest ones within a few minutes of this photon trap. The sun was JUST rising over my shoulder. I was standing in the long shadow of the ridge I live on.

Getting to see weather move over those high ridges is a rare treat from this far away. These huge blocks of the earths crust uplifted during a major tectonic compression episode called the Laramide “Orogeny”. (Google Word of the day) Cloud peak is 13,175 feet. The same compressional forces that uplifted the peaks, also downwarped the adjacent basin to the east toward my camera. This deep basin is called the Powder River Basin.

The Powder River basin is a major source of clean burning coal in the US. The burning of this coal generates 30 percent of the electricity generated in the United States. My ranch coincidentally sits directly on the western most edge of the Wyoming Black Hills. It is actually JUST east of the edge of the Powder River Basin. If I drive 2 miles west, I start to see alluvial fan sediment. These sediment fans stretch all the way from the Big Horns.

Those long fans of sand/gravel/silt and clay, dissected into ridges by huge rivers washing off the peaks during glaciation. These alluvial deposits are far reaching, called the “Tullock/Fort Union” formation. The first two sets of ridges are all Tullock, as are the hills behind them out to the Mountain range. They are all made of sediment that traveled from the Big Horns when they were MUCH taller.

Major Mountain Chain sized Anticlines and Synclines resulted from continental wide compressional forces. Huge were those forces bending even the underlying crystalline Pre-Cambrian rocks. The rocks weathering to sand and clay washing off of those peaks filled the basin and washed all the way… well just about to my front door.

View from up on Ridge one here on ranch. The window to the Big Horns is IFFY this time of year from this far away. My truck/tripod is 130 miles out for this capture off the highest point around the place. The timing on this was a few minutes before sunset. Full Screen is a good choice for this. Twilight over the BigHorns this night was so obviously gorgeous. I had to resort to a short time exposure to catch it. The timing on this sunset is very late in Civil Twilight.

Civil Twilight after sunset ends about 28 minutes after the sun goes down 8 degrees under the horizon. It’s usually the best time to get those crimson and yellow skies. The yellow is Alpenglow. Atmospheric Ice causes this phenomena caused by refracted light passing through. Only the red wavelengths which have survived through hundreds of miles of atmosphere light the cloud deck. Orange as this is a mixture of the two effects.

The long lenses I use crush the perspective of distance. I’m almost always using telephotos to bring in just the BigHorn Mountains filing the whole frame. It takes about a 800 mm long focal length to fill the camera frame side to side with the tallest part of the range. The black ridge at the bottom is 40 miles out. The clouds behind the range are around 200 miles out I would suspect. The distance is hard to put into proper frame. Those 13000 feet high mountains appear smaller than the thumb on my outstretched arm from here from my eyes unaided perspective.

Boy this is a classic Pastel Western Mountain Scene. The Big Horn Mountain Chain rises from the between basins on either side of the huge tectonic uplift. A 130 mile long landscape with the first ridge past the trees being 40 miles away from the camera. Take in mid-twilight about 15 minutes after sunset. It was quite dark considering how well this came out.

Photographic Musings:

Perspective’s with a little foreground bokeh (google this) is unavoidable working low light twilight conditions. This pastel scene was difficult to get as I didn’t have a tripod with me at that time. I was just resting them camera on a vehicle body.

The only ways to gain light in your camera working in low light is, to either 1: turn down your f-stop numbers (open the aperture up which as a side effect, reduces your depth of field), 2: longer exposure (I was rested only, no tripod so 1/10th of a second is about as long as you can do rested. That is holding the back of the camera while resting the lens on something. OR 3: Turn up camera sensitivity which will give you lower quality grainy images to gain light by a Higher ISO number. Lower ISO’s will give you a fine grained image but it takes more ambient light than this to use.

I had to give in somewhere, f-stop it was. Turn it down to f11 on this 400 mm telephoto lens capture.

The width of those 13000 feet high mountains appear smaller than the thumb on my outstretched arm from here. You are quite zoomed in here. 👀📷
