This image was shot on a relatively cool morning in the middle of January. While there was some snow on the ground, it wasn't an issue climbing to the perch that's located just across from the North Window here in Arches National park.
On this day as I was making a duplicate of the classic of Turret Arch through the North Window, a fog arrived from the east that eventually obscured the area. The beginnings are just being seen to the left of this image.
I retreated from this perch to avoid being caught in the fog with potentially slippery freezing moisture conditions.
One thing I figured out after making the strenuous climb up to the perch here is my down jacket is extremely susceptible being degraded by sweat. I sweated like I normally do which was absorbed by my jacket. Eventually that cause the down to lose much of its heat retention capabilities. As awesome as down is for retaining heat, it's very susceptible to me and my ability to sweat through anything.
