In 1890, Adams married Alida Joslin Reynolds and the couple honeymooned in Estes Park, Colorado. The couple would later move to Estes Park in 1905, when construction was complete on a home and studio. Estes Park with a view of Long's Peak, was a frequent subject of his paintings. He also traveled south into New Mexico and north into the Tetons and Yellowstone Park and west to the mountains in California. In 1893, Adams became a charter member of the Denver Artists Club.
In the early 1920s, he moved to Laguna Beach, California, where he remained until his death in 1942. In this period, he painted marine scenes and views of the Sierra Nevada mountains.
During his lifetime, he completed several thousand paintings. Examples of his work can be found in Colorado at the University of Colorado at Boulder, the Denver Art Museum, and numerous private collectors.
