Shown here is a medium-long exposure image that I took at night with my iPhone 13 Pro while backpacking in the Indian Peaks wilderness near Rollins Pass on September 10, 2022 at 8:30 PM. In the foreground my tent is captured and is illuminated by a headlamp inside on the red-light setting. In the background, down valley, clouds are captured that are undulating and hanging in the valley all the way down into Nederland and then into Boulder beyond that. The image was taken at ~11300ft of elevation. I believe these clouds can be characterized as fog that is orographically influenced by the mountains and valleys below it. I would estimate that the fog is hovering around 10800-10200 ft of elevation at its highest in this photo. The most proximal Skew-T graph for when and where this image was taken is pictured below and shows that the atmosphere in this photo is stable, as indicated by the CAPE index being equal to 0. Based on the skew-t graph there are no extremely obvious indications that we would be certain to see clouds, however we could expect to see the most likely formation of clouds around 10400ft which is the case in this photo. This indicated that the skew-t graph is potentially partially representative of what is going on in the image despite the fact that it’s measuring Western Slope weather as opposed to Front Range weather. A time lapse video of the fog pictured can be seen below as well, illustrating the undulating gravity and buoyancy forces at play causing the valley to look like a sea of fog.

I love the colors and the lighting in this shot. I think you made a good use of light. I don’t know if this is the compression or your editor, but there are noticeable bands of color in the sky, those are a little distracting. But that’s an easy fix.
I want to camp there! The fog looks so unreal in the timelapse its like you’re looking at an ocean of clouds. The way it behaves, has waves, and crashes against the mountains is beyond cool.
You did a really great job with this image, especially at night, it is a very interesting and beautiful image.
I really like the variety of colors in this photo. The orange glow of the tent is really cool and adds a lot of contrast. One question I have is what altitude this photo was taken at? I also really like that you can stars in the sky.
Seeing clouds at night is really cool! I like the tent in the photo because it does add contrast between the dark sky and the dark ground.
I really like the lighting in this image. The light off of the tent contrasts against the dark ground which contrasts against the bright clouds and light sky. The softness of the clouds really adds to a sense of tranquility.
This is a great image. It reminds me of looking at the sea from a coastline, the clouds are not the most prominent part of the image, but they really locate the image well. The nighttime moon in the background illuminates the clouds well.
I really like this image because of the view above the clouds which is a very unique view. Also, being able to see the shape of the clouds form to the mountains and valleys below you is amazing.
