The Lassen Association bookstores in the Kohm Yah-mah-nee Visitor Center and Loomis Museum are operated by the non-profit Lassen Association. The association donates revenues from sales to the park for educational, research, and environmental programs. Thus, your purchases from the Lassen Association Store directly benefit Lassen Volcanic National Park. For visitor center and Loomis Museum operating hours click here.
