While on vacation in skagway (june 2019), alaska we took the train ride that goes into canada and turns around to return back to skagway. while on the return trip i was taking photos with my cellphone, samsung 8. the photos were taken through an open window of the scenery with no obstructions. after taking the pictures i would look at them. in one particular picture i noticed a silver gray object in the sky above the mountains. i looked out of the window and could not locate the object i accidentally took a picture of. i zoomed in on the picture and the silver gray object did not look like any aircraft i had ever seen. maybe it's just an odd angle of an airplane, but i can't be positive. anyway, i thought i would send this in to mufon in case there is are or were any other weird sightings in this area. i have never reported anything like this before. as a military brat and retired law enforcement officer it would not have been in my best interest. thanks for taking a look at it.
