Reflection. Lake is. located in the northwest corner of Lassen Volcanic National Park, and a short distance east of Manzanita Lake. The lake was originally known as Stockton Lake. It was so named after John Stockton, a Shasta County physician, surveyor and civil engineer. In 1875 Stockton, along with William Coffey had plans to develop it into a fish farm, but that proposal never went anywhere.
In 1926, B.F. Loomis purchased a 40-acre parcel near Reflection Lake. Loomis an avid park supporter offered the property. to the park, in hopes the park would make the headquarters there. In 1927, the park announced Mineral would be the site for the headquarters. The decision did not deter his support of the park. Loomis went ahead and built a museum there. On February 4, 1929, Loomis donated the property to the park. That summer the park in consideration of the donation, granted Loomis a life estate to five acres that allowed to him continue to maintain the museum and gave him the privilege of building a residence and photographic studio. Loomis died 1935.
