About this work
Technique & Style
The horizontal format emphasizes the vastness of the Green River valley, with meticulous attention to the striated rock formations and distant peaks.
Executed in 1881, Thomas Moran’s oil on canvas employs layered, translucent glazes to render the stratified cliffs and atmospheric recession, a method characteristic of his mature style. The horizontal format emphasizes the vastness of the Green River valley, with meticulous attention to the striated rock formations and distant peaks. The handling balances broad, atmospheric washes with fine detailing in the foreground vegetation, while the overall tonality favors warm ochers and muted greens under a luminous sky.
The canvas support measures 63.5 × 157.5 cm, allowing for an expansive panoramic composition that underscores Moran’s Romantic landscape tradition.
History & Provenance
Thomas Moran created the oil-on-canvas landscape Green River Cliffs, Wyoming in 1881. The work's early ownership is recorded in a 1994 sale catalogue and Thomas Moran Papers, which identify Mr. Clapp or Dr. Williams of Chicago as initial owners, followed by the Julien Levy Gallery in New York. Frank Glenn of Kansas City subsequently owned the piece before Frederick W. Allsopp of Little Rock purchased it.
Allsopp gifted the painting to the Museum of Fine Arts, Little Rock (now the Arkansas Arts Center) in 1937. The institution de-accessioned the work in 1983, selling it through Ira Spanierman Gallery to William I. Koch. After a Christie's auction in New York on November 30, 1994, the painting entered the collection of Vern Milligan of Denver.
Milligan and his children donated the work to the National Gallery of Art in Washington, D.C., in 2011.
