Heidi Gustafson, who has spent the past five years collecting and working with ocher, walks along Whidbey Island’s Double Bluff Beach, off the coast of Washington, in search of the material. She came to scout this area, where she spent time as a child, after recalling its interesting cliff exposure.Some ochers, Gustafson believes, are calling out to be turned into a pigment. Others are more resistant. Those ocher fragments are either returned to their point of origin, or, if Gustafson cannot get back there, placed outside in a stone graveyard of sorts that she has created in the forest near her cabin. A few of her ocher-based artworks hang on the wall.
