In the spring of 1928, he completed his first Sierra Nevada landscape, entitled
Olivas Pack Station, a scene in
Lone Pine.
Mount Whitney towers in the background. On 13 March 1928, Santa Paula was flooded when the
St. Francis Dam, owned by the City of Los Angeles, collapsed, killing 600 people and destroying nearly 1200 homes. Clunie returned to house painting temporarily as the town was rebuilt, but still managed to complete 19 paintings that year. Clunie was now developing a distinctive style as a landscape painter, and credited
John Ruskin as an influence, especially his book
Modern Painter, published in 1881. He was now supporting himself by selling paintings out of his home studio, and brisk sales continued into 1929. He spent the summer of 1929 in the Sierra with his wife, painting in
Yosemite National Park and the
Mammoth Mountain area, followed by an 8-week stay in the
Palisades peaks east of
Big Pine. He hired the Glacier Pack Station to move his gear by
mule, setting up camp on a knoll between Fourth Lake and Fifth Lake. He completed at least 14 paintings in the Palisades, and had found his artistic home, as he would return to the same campsite about 30 times over the years. He met California mountaineer and nature writer
Norman Clyde during his 1929 painting trip to the Palisades, and they became lifelong friends. The two men shared an enthusiasm for prolonged wilderness sojourns, and in particular, a love for trout fishing. Clyde's biographer Robert C. Pavlik observed that "The two men shared a common philosophy as well. They shared a love of the mountains and each tried, in their own way, to capture the essence of their meaning." Clyde would often visit Clunie's campsite over the years to rest up between ascents, and referred to his camp as "The Palace Hotel". Twenty-five years later, on 9–11 September 1954, a severe early-season snowstorm hit the Sierra Nevada, and Clyde and a companion took shelter in Clunie's camp for four days. His 1929 Sierra Nevada paintings were received with great praise, and he sold at least fifteen paintings in the months that followed. The Biltmore Salon in Los Angeles arranged an exhibition of his paintings, and some were included in a group showing at the Stendahl Gallery.
Los Angeles Times art critic Arthur Millier said of the paintings at the Biltmore, "Mountains are humbly approached by Robert Clunie, a young Santa Paula painter, whose paintings were for the first time shown to a few local critics and dealers in a sample room at the Biltmore. The works displayed made a very favorable impression on this reviewer who believes the artist to have already achieved some splendid Sierra painting, and to be in line to go much further." Millier went on to praise Clunie for his "careful observation of nature, a fine feeling for the grandeur of composition presented the artist by the architecture of the Sierras, and an eye for light as the medium that binds together the separate masses seen in nature." A reproduction of a Clunie painting called
The Cliff illustrated the article. In the midst of these positive developments in Clunie's career, the stock market crashed on 29 October 1929. In the aftermath, customers canceled orders for paintings, not a single painting sold at the Stendahl Gallery show, and when Clunie went to pick up his unsold paintings, the most praised of them,
The Cliff, had somehow been lost by the gallery. In the wake of this bad experience, Clunie decided to never again sell through galleries, and instead sold his work directly to collectors for the rest of his career. Better news was the birth of his son, Robert Kent Clunie, on 14 November 1929. Clunie joined the
California Art Club and the Painters and Sculptors Club, giving him an opportunity to exhibit his work outside of commercial galleries. The Los Angeles Times again praised his work on 21 December 1930, observing "for Robert Clunie the crags stand still with the utter stillness of hard granite while he paints the deep shadow tones of granite above a blue pool cut by the gold of a sand bar. In another canvas by him they thrust sharply into the sky, jostling each other in the impestuous force of upheaval." His painting
Coast of Carmel was selected for the California Art Club Exhibition of 1931 at the Los Angeles Museum, which is now called the
Los Angeles County Museum of Art. During the 1930s, Clunie received several commissions to paint large dioramas at the
California Exposition & State Fair in Sacramento. Crowds would gather to watch him paint. In 1935, Clunie spent two months painting in
Taos,
New Mexico. Local painter
Walter Ufer praised Clunie's work there, urging him, "Stay in Taos, Robert. You are giving it a new look."
Ansel Adams called one of his Taos paintings,
Vaya Con Dios - St. Francis of Assisi Mission - Moonlight a "masterpiece". In February, 1937, Clunie won first prize in the Academy of Western Painters Exhibition for his painting
Saginaw River. The painting won third prize at the California Exposition and State Fair in 1938. He painted in the
Grand Tetons each summer from 1938 to 1941, and the Los Angeles Times described his Teton paintings as "impressive" and said that "the artist has approached his subject with a bold, strong technique combining the finest in art with a reality and geographic correctness which has excited the highest admiration from the rangers in charge of the district as well as art critics". He became friends with mountaineers
Paul Petzoldt and
Jack Durrance in the Tetons. When Germany invaded Poland in September, 1939, Clunie developed
melancholia and was unable to paint for a year. Clunie was an enthusiastic chess player. He beat
Reuben Fine at chess on 15 September 1940. Clunie was the only player who beat Fine, a
grandmaster, during his two-month tour of the country. When the United States entered
World War II, Clunie spent six months doing
camouflage painting at Navy refuelling depots at
Morro Bay and
Cayucos, California. In 1942, Clunie went back to his favorite painting location in the Palisades peaks, and returned every summer until 1966, usually spending about two months in the wilderness. He would usually hire five mules to pack in his gear. == Postwar years in Bishop, California ==
