A Stairway To Paradise

was seen today and here it is incollage format  . This  superb cloud phenomenon  began and was over in no time. It's on my hard drive for ever. .
Top L is 15:44,   Top R 15:45,  Bottom L 15:46 , Bottom R.. 15:47

It pays to enjoy coffee outdoors in very fresh air. My knowledge re clouds is limited . Maybe some one knows what created this .:
