It was an Icy Alpenglow Morning right at sunrise up yonder on the ridgetops. The main show over my shoulder is usually yellow (ish) but this backshow is Pink. This pink back show is called the “Belt of Venus” which is often on going while your watching the sunrise, you miss this show. Several image from this particular morning made it through the “sieve” I use to determine which photo to work on.
Alpenglow is the result ice in the air lighting up with the bright first pink starting about 40 minutes before sunrise… and then gradients to other nearly pure primary colors to Lavender at times up high. The Blue Line UNDER the Pink is the Shadow of the earths horizon. As the sun rises that blue band shrinks eventually disappearing just as the sun rises. The red/pink will often work down on the “Red Hills in the distance enhancing their already red rocks (Clinker) with the extra colorcast.
The hoar frost covering any exposed surface made for a winter wonderlands for a photographer with time before sunrise. Hoar Frost usually forms on objects disrupting air flow. The air full of moisture under freezing conditions. DIrect condensation of that vapor from supersaturated air is greater then 100%. The formation of hoar frost is similar to the formation of regular dew with the difference that the temperature of the object on which the hoar frost forms is well below 32 degree F., whereas this is not the case with dew. Hoar frost crystals often form initially on the tips of plants and or other objects. I’ve seen vehicles, fences, tires, plants and even other icicles with Hoar Frost on them. The largest I’ve seen had frost feathers/needles almost 2 inches long.
I’ve been on this spot many times. It is not easy to gain access to Midwinter. I have discovered that gaining elevation is a necessity required to acquire views such as this. 400 feet higher up here than where I live on the lower lip of this ridge. This rare back-lighting effect (colorcast) is accurately produced here exactly as I experienced it. The Red “Belt of Venus” in the sky background is from the same color light reflected in the atmospheric ice. The White Snow acting like a projector screen. I see a few of these a year historically. The snow and the hoar frost created “Pine Noodles” out of the needles. Witnessing and understanding what is happening below the surface are two different things however 🤔📷.
The snowstorm began at nightfall but ceased at mid-night. Bedded down were all the animals. The crisp wet morning accented the twilight. It might take half an hour of pre-sun travel to gain access this high remote ridge. There are no maintained roads up here off the county road. Busting drifts you can’t see is always a challenge…. Stuck describes a situation my 15 year partner Jeep Grand Cherokee I just traded in has never been. They ride like a board sadly under these backcountry two track roads. New ride 🙂
The Lone Tree and a few of it’s children surrounding the old soldier. These trees live in some very harsh conditions. They are almost all twisted grain under that bark from the high winds at the ridge.
This 40 mile landscape overlooks the Trail Creek Drainage. Off in the distance to the Little Powder River Drainage. The Mountain Ridge on the horizon is a reference point here. The camera is at the same elevation as the saddles between the peaks in the distance. This is a BIG valley / river drainage. The Big Horn Mountains had filled that big valley between the far hills with where I stand here.. The “Little Powder River, a 20 foot wide river most of the time removed all that sediment here to there….. Humm.. The “Alluvial Fans” (google this) from the Big Horn Mountains washed up to our doorsteps from 130 miles distant. Those have been bisected and removed by that little river. It’s drainage fingers cover a large area too. This is just a dry environment. This geomorphological process has taken a while.
Our ranch literally sits on the geologic inflection point between the Black Hills Uplift to our east and the Powder River Basin west (this view) The range distant to the horizon earned it name, the “Red Hills”. (I wonder why?)😜 Morning Red LIght is always illuminating those peaks for me.
