Hi, all,
I've been in touch with Allan James about getting a copy of this field
guide for Branner.
He's charging $7 for it. He has more copies. If you want to buy one,
contact him
directly at <aJames@sc.edu>.

Tracking Hydraulic Mining Sediment in the Sierra Foothills and
Sacramento Valley
Sunday, April 15, 9:00am - Tuesday, April 17, 4:00pm
Organizers/Leaders: Allan James, University of South Carolina; Michael
Singer, University
of California at Santa Barbara; Rolf Aalto, University of Washington, Seattle
Trip Capacity: 30
Cost/person: $325 (includes transportation, two-nights accommodations,
field guide, three
box lunches, one dinner banquet, two afternoon wine receptions, snacks
and drinks each
day)
This trip will visit hydraulic gold-mine pits, locations along
mountain rivers below the
mines where deep gravel deposits continue to be reworked, sites in the
Sacramento Valley
where fine-grained deposits are exposed, and depositional areas in
Sutter and Yolo
Bypasses. We will visit mining areas in the Sierra foothills and
concentrate on mine
tailings there and in the Sacramento Valley. We will highlight
linkages between episodic
production of mine tailings, their reworking and deposition
downstream, including in
flood bypasses. Methods and some preliminary results of an on-going
study that involves
inventories and geochemical fingerprinting of historical sediment will
be discussed. Some
vigorous hiking will be undertaken up Greenhorn Creek on the first
day; river shoes are
recommended (sandals or canvas sneakers work well), and into upper
Shady Creek on the
second day where sturdy walking shoes or boots will be favorable.
Participants should
bring money for breakfasts and one dinner.
