Here is some information that might provide you with some insight.
The Aleutian World War II National Historic site, maintained by the NPS, has some introductory and bibliographical information on the evacuation and internment of Aleutians beginning in 1942. One text by Charles Mobley, entitled World War II Aleut Relocation Camps in Southeast Alaska, is an archaeological report that explores the war's impact on the local Aleut community, continuing through the evacuation procedures, and evaluating its status as a historic site. Both links will take you to the NPS website and PDF version of Mobley's report:
The NPS also lists the Aleutian Pribilof Islands Association as another resource on Aleutian internment. This association works with the Unangan people in the region through different economic and community programs; one of which is the cultural heritage and history. The association retains Aleutian documents and photographs relating to the evacuation and internment and they can be contacted for further information below:

Records regarding the creation of the policies that led to Japanese internment might provide some insight into why the Aleut Native Americans were interned in these camps. These records can be found at the Franklin D. Roosevelt Library and Museum, which can be contacted via email at Archives.FDR@nara.gov. The Harry S. Truman Library and Museum also has materials on this topic, and can be contacted via email at email@example.com. The War Relocation Authority (WRA) was a United States government agency established to handle the internment of Japanese Americans during World War II. The majority of the Records of the War Relocation Authority (Record Group 210) are in the custody of the National Archives at Washington, DC - Textual Reference (RDT1), which can be contacted via email at Archives1reference@nara.gov. The War Department Western Defense Command was also involved with the removal of Japanese Americans. These records are included in the Records of U.S. Army Defense Commands (World War II) (Record Group 499). Some of Record Group 499 records are in the custody of RDT1, while others are in the custody of National Archives at College Park - Textual Reference (RDT2). Please contact RDT2 via email at Archives2reference@nara.gov.
Keep in mind that due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from the presidential libraries and from RDT1 and RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
