[Geysers] Steamboat photos

[TSBryan at aol.com]

I am attaching two photos of Steamboat, both taken from the online  
Yellowstone slide file, so no doubt many of you have seen both of them. Thing is  
this -- looking at the background clouds, general lighting, and etc., it is  
quite obvious that these photos show the same eruption. But one is 
identified as  by Lang and Dick in 1963 (#05757) and the other as by Mackin in 1964 
(#05756).  The date on one of these must be in error. Anybody know which one 
is  correct?
