Gary Snyder.
 
Four Seasons Foundation: 1965. Signed first edition. Chapbook. Near fine.
 
Robert Hass, former poet laureate of the United States: ''Snyder is one of the most gifted poets from a gifted generation of poets . . . As for 'Mountains and Rivers,' it tracks his thinking from a young anarchist and radical environmentalist to a more subtle sense of environmentalism. And yet, remarkably, the cycle has the force and concentration of a very shaped work of art.''
