After graduating from college, Hanson entered the art trade as a professional, inspired by landscapes and vantage points only beheld by the most adventurous. Rock climbing among the brilliantly colored cliffs of Nevada and Utah, watching the seasons and the light change daily across the desert, provided endless inspiration for her work. In these beautiful surroundings, Hanson decided firmly to dedicate herself to creating one painting every week for the rest of her life. She has stuck to that decision ever since and has for the past decade been developing a unique, minimalist technique of placing impasto paint strokes without layering, which has become known as “Open-Impressionism.” As other artists began emulating her painting techniques, Hanson was credited as the pioneer and originator of this contemporary style. Through the years, Hanson has continued to use the outdoors to inspire a huge collection of work. She visits the Colorado plateau every year, backpacking and hiking through areas such as Zion National Park, Canyon de Chelly, and Monument Valley. Other favorite haunts include Paso Robles, Joshua Tree National Park, and the Anza-Borrego desert. Erin Hanson transforms these landscapes into abstract mosaics of color and texture, her impasto application of paint lending a sculptural effect to her art. Her oil paintings stand out in a crowd, bringing a fresh new look to Western landscapes.
