Sierra Nevada, California.
Lit-par-lit injection migmatite at the contact between the Cape Granite and the Malmesbury Group (meta-)sediments.
Two sets of crenulations create a "fishscale" effect when this sample is turned in the light. Collected on the west side of an island just south of Scalloway.
