Cloud covered object with black parallel column from sky to the ground

While driving from work (Highlands Ranch, CO, to my apartment in Colorado Springs, CO, while stopped I took a picture of the Sun descending behind the Rocky Mountains, fairly common thing for me to do, on the evening of 06/08/17 at 2028.  I am sure at the time I didn't notice anything unusual or would have thought more about it, so at that moment it was just a sunset.  I transferred my pictures from my Iphone SE to my laptop and never thought about it, as I was working a lot of hours at the post office.  
Well yesterday (06/19/2019) I am going through my pictures on my laptop and came across a very odd one.  Towards the sunset there is a large dark parallel column from the clouds to the ground.  I zoomed in and at the top there appears to be a single stationary object in the cloud, silver with a very flat top.  Thought it might be just part of the cloud, but never seen a cloud like that.  There is nothing that was on the window of my car that would have caused t! his or on my phone.  Not sure why but I took a second picture zooming in on that area and there is no black parallel column.  Attaching both pics for you to look at.  I was afraid to show or tell anyone my suspicion cause, I didn't want to be looked like I was crazy.  Only showed one other fellow photographer and she said it looked weird too.
