Thank you to all of you who responded, either directly to me and/or through the listserv. The consensus seems to be that the pool is Shelf Spring and that the photographer was referring to "Pink Cone." After comparison with a picture I took in the mid 2000's when I was (legally, with NPS permission and accompanied by a person in uniform) able to view Shelf Spring from the immediate vicinity, I agree. And yes, Udo, gazers find a variety of ways to get their geyser fix when they can't get to the Park! Lynn -------------- next part -------------- An HTML attachment was scrubbed...
