This print is of a cave near Tofino, BC, Canada.
A linocut is a relief printing process introduced in the 20th century, employing a piece of thick linoleum and tools similar to those used in woodcutting. The smooth, easily worked surface allows bold, simple images to be made by cutting away negative lines and areas. After the block is inked, prints are taken in a press or by hand.
