Introduction: Where are the "hot" earth science projects in the Jemez Mountains region
Fraser E. Goff


When I first came to Los Alamos in 1978, I was told that 1 ought to
look carefully at the. volcanic rocks and stratigraphy of the Jemez Mountains
region because this was truly a classic geologic spot, especially
Valles caldera, But I was also sold that there really was not much science
left to do here because, after all, the Jemez had already been mapped by
R.L. Smith, R.A. Bailey, and C.S. Ross.

The sheer beauty of the Jemez had an instant effect on me. Within a
couple months of being hired by the Laboratory, l started to poke. around
in Callon de San Diego, down in the southwest Jemez, because I had heard
there were hot springs hidden in the canyon. and I had a love affair with
hot springs, Besides, I had been hired to work Oil geothermal enemy (never
mind that it was Hot Dry Rock), and it seemed like a young caldera with
hot springs ought to provide something interesting to investigate.

The plumbing of the hot springs in the canyon was the first thing
pondered. A geothermal well was drilled at Jemez Springs and I volunteered
to take fluid and carting samples. Then a detailed geologic map
was needed of the canyon to define structural controls on fluid flow.
While mapping, s was amazed at the. large size of the hot spring system
at Soda Dam, How long had it taken to form the travertines and was the
formation of thew ancient deposits constant or cyclic?
