[Geysers] Two articles on Norris Geyser Basin in Yellowstone Science

[Ralph Taylor]

I received the latest issue of Yellowstone Science today, and noted two
geyser-related articles.  The first article, "Control of Hydrothermal Fluids
by Natural Fractures at Norris Geyser Basin", is by Cheryl Jaworowski
(Geologist working for YNP), Henry Heasler (Yellowstone's Park Geologist),
Colin Hardy (Project Leader of Fire Behavior Research Work Unit of the US
Forest Service) , and Lloyd Queen (Professor of Remote Sensing at University
of Montana).  It includes some interesting illustrations showing surface
temperatures overlaid on aerial photographs. 
 
The second article, "Norris Geyser Basin's Dynamic Hydrothermal Features" is
by David Shean and discusses the use of historical aerial photos to detect
change.  It includes numerous photos from 1954 to present showing various
features (The Reservoir, Porkchop Geyser, the Ragged Hills) as they change
over time.
 
If you are interested in Norris changes and the research that is ongoing to
study changes in thermal areas using remote sensing, this is a "don't miss"
issue.
