Oliver falls out with his boss and quits. Soon, Susan learns that all is not well in the mine. Susan publishes her experiences in a magazine article and is paid. After she becomes pregnant, she is happier and makes friends.

Oliver spends his days in the mine, and Susan is lonely. Susan’s reputation as an artist proceeds her, but she does not fall in love with the locals. Susan’s story is told in an epistolary style, through letters written to her closest friend, Augusta Hudson: After a long journey to California in the late 1800s, Susan arrives in her new home: a cottage on the outskirts of a lively mining town. Susan and Oliver were married for 60 years and faced tragedy, infidelity, jealousy, and even long separations. Lyman accepts the help of a young college dropout, Shelly Rasmussen, in sorting through Susan's papers, which detail Susan's experiences as a writer and an artist in the mid- to late-19th century. Lyman originally plans to write a novel about Susan's professional experiences but writes about her marriage instead. To pass the time, Lyman moves into his old family home and begins to study his family’s history, charting his grandmother Susan's emergence on the New York high society scene before she meets and marries Oliver Ward, a mining engineer. While Lyman was in the hospital convalescing, his wife, Ellen Hammond Ward, left him for Lyman's surgeon.

The angle of repose is a representation of the angle of internal friction however, it tends to be governed by grain shape such that the slopes of most piles of loose, dry grains of natural soil are in the range of 28° to 34°.

Grains that are chemically and mechanically separate from each other form a mass that can be excavated with relative ease, and the excavated material can be placed in a pile that attains a conical shape with slopes that are called the angle of repose (Fig. Soil consists of grains of minerals or rock fragments in a range of sizes (mm to m) from very fine to very coarse (clay, silt, sand, gravel, cobble, and boulder-size). The angle of internal friction is a physical property of earth materials or the slope of a linear representation of the shear strength of earth materials.Įarth materials that are unconsolidated and uncemented typically are called soil by engineers and geologist and may be called sediment by geologists.
