1982. Cyanotype, intaglio, and relief print. Blue, gray,  red-orange and black  on 21 1/2 X 15 in. papers, 29 X 20 1/2 in. Japanese paper. No. 69, from variable edition of 141 prints. Signed lower right. 

Artist's Statement: "This print is from a series of 141 trial proofs and artist's proofs in "cycles" of around 15 each, and each in a different color combination. I made them in the processes of cyanotype, woodcut, and intaglio techniques. This one was part of a series I made in Bozeman, Montana, during a workshop I gave there at the University. The result of all this is a series of monotypes. The images are from three sources: A map of the Colorado River, at the Crossing of the Fathers; the leaf shape I call locus--the path of a moving point (drawn to establish data in a computer program);  Finally, The Great Wave was drawn from the famous print by Hokusai." This print is one of the few with the "Two Loci" print in the bottom.
